CN2B Mobile Computer User’s Manual 753Installing ApplicationsThere are multiple ways to get an application to your CN2B Mobile Com-puter; like there are multiple ways to package the application for delivery.
Chapter 3 — Installing Applications76 CN2B Mobile Computer User’s ManualPackaging an ApplicationUse any of these methods to package an application for installation:• For very simple applications, the application itself might be the only file that needs to be delivered.• It could be a directory structure that contains the application, supporting files like ActiveX controls, DLLs, images, sound files, and data files.• Or, you could package an application via a CAB file.Consider any of the following when choosing a location into which to store your application:• In the basic CN2B Computer, there are two built-in storage options: the Object Store and the Persistent Storage Manager (PSM). The Object Store is RAM that looks like a disk. Anything copied here is deleted when a cold-boot is performed on the CN2B Computer. The PSM is an area of storage which is embedded in a section of the system’s FLASH memory. This storage area is not erased during a cold-boot. It may, how-ever, be erased during the reflashing process. In addition to storing appli-cations and data files, you do have the option to store a persistent registry to the PSM region.• If the optional Secure Digital storage card is in the system, then consider this card the primary location for placing an applications install files. This storage card creates the “\SDMMC Disk” folder.• Use the small nonvolatile Flash File Store region to hold CAB files that rebuild the system at cold-boot or install applications from a CAB file into the Flash File Store so they are ”ready-to-run” when a cold-boot is performed. Since the FLASH in the system has a limited number of write cycles, do not use the Flash File Store for excessive writing pur-poses; however, reading is okay.Files copied to any of these locations are safe when a cold-boot is performed on a CN2B Computer — providing the AutoRun system is installed in the appropriate location You can find this system in the CN2B Management Tools portion. Copying a CAB file to the “\CABFILES” folder on one of these cards automatically extracts that CAB file on every cold-boot to ensure that your system is properly set up (see page 83).
Chapter 3 — Installing ApplicationsCN2B Mobile Computer User’s Manual 77Installing ApplicationsConsider any of the following options to get the package to the preferred location on your CN2B Computer: Microsoft ActiveSync, FTP Server (page 78), Secure Digital storage cards (page 78), or Registry (page 79).Using Microsoft ActiveSyncThe Microsoft ActiveSync tool is located on the CN2B Companion CD. See Chapter 2, “Windows Mobile 2003” for information about this tool as pro-vided by Microsoft Corporation.This can be a serial, USB, InfraRed, or 802.11b/g ActiveSync connection. Files can be copied using File Explorer on a desktop or a laptop computer. This is usually good when updating few CN2B Computers.These instructions assume that Microsoft ActiveSync was installed onto your desktop and is up and running. If not, go to Chapter 2, “Windows Mobile 2003” for an URL from which to download the latest application.1Connect your CN2B Computer to your desktop computer via an Active-Sync cable.2Wait for a “Connected” message to appear in the Microsoft ActiveSync application to signal a connection to the CN2B Computer. If necessary, select File > Get Connected to initiate a connection.4From your desktop, select Start > Windows Explorer, then browse the “C:\Intermec\CN2B Mgmt Tools\CabFiles” path for any CAB files needed for your CN2B Computer. Select the appropriate file, right-click the file for a pop-up menu, then select Copy.Note: These instructions assume the CN2B Management Tools were installed on your desktop.3Click Explore to access the Mobile Device folder on your unit.
Chapter 3 — Installing Applications78 CN2B Mobile Computer User’s Manual5Within the Mobile Device directory, go to the directory where you want the files located on the CN2B Computer, do a right-click for a pop-up menu, then select Paste.6When all of the files are pasted, perform a warm-boot on the CN2B Computer. When the computer reboots, wait for the LED on the top left of your keypad to stop blinking. Tap Start > Programs > File Explorer to locate the newly copied executable files, then tap these files to activate their utilities.Using the FTP ServerThe CN2B Computer has a built-in FTP Server that connects to a network via 802.11b/g or WAN (Wireless Access Network). This allows connec-tions to the CN2B Computer to perform file transfers or computer man-agement functions. Another benefit is you can create FTP scripts to automate the process of copying files to the CN2B Computer. This option is good for when a large number of CN2B Computers need updating. See Chapter 7, “Programming” for more information.Copying a Secure Digital Storage CardUse the following steps to install an application using a Secure Digital stor-age card:1Suspend the CN2B Computer and remove its Secure Digital drive, which holds a Secure Digital storage card.2Using a Secure Digital Adapter card, place the Secure Digital drive in your desktop PC card drive.3Create a subdirectory on the PCMCIA Secure Digital drive in which to store your application.4Copy your application, data files, and all required DLLs and drivers to the subdirectory created on the Secure Digital drive.5Add your application to the AUTOUSER.DAT file on the “\SDMMC Disk\2577” directory with the following statement: RUN=\<your directory>\<yourapp.exe>where your directory is the directory on the Secure Digital storage card where the application was installed, and yourapp.exe is the name of your application. Finish the “RUN=” statement with a carriage return linefeed combination. There may be multiple run statements in the file.6Remove the Secure Digital card from your desktop and reinstall it into the CN2B Computer.7Warm-boot the CN2B Computer to add these files to the Secure Digital storage card.If the AUTOUSER.DAT file is found and the “RUN=” statement is cor-rect, the task manager launches and executes your program on startup.
Chapter 3 — Installing ApplicationsCN2B Mobile Computer User’s Manual 79Replicating Settings Using the RegistryThe following information updates the registry on your CN2B Computer, confirms the registry update, then copies the information onto other CN2B Computers in your network.If you are using DHCP, no changes are necessary.If using Static IP, the new CN2B Computer has the IP address of the origi-nal CN2B Computer because the copied registry includes this information. When you change the IP address using the Intermec Settings applet, the information is lost when a warm-boot is performed, and the original IP address is used. Load the REGFLUSH.CAB file before running the Registry Save applica-tion. Once you do, performing a warm-boot keeps the new IP address.To install the Registry Save application after a cold-boot is performed, change the properties of the REGFLUSH.CAB file to that of read-only. Using ActiveSync, copy the CAB file to the “Flash File Store\CabFiles” folder on the CN2B Computer, then perform a cold-boot to load this file.Deleting the Old Registry File2Look for a “registry” file. If one exists, select to highlight that file, press and hold for a pop-up menu, select Delete, then Yes to remove this file.Using the RegFlush CAB FileContact your Intermec representative about getting a copy of the REGFLUSH.CAB file.1On the original CN2B Computer, select Start > Programs > File Explorer, then tap My Device > Flash File Store. Scroll down to the bot-tom of the list of files and folders, press and hold your stylus in the white area beneath for a pop-up menu, then select View All Files.

Make sure the ActiveSync application on your desk-top is up and running and connected to your CN2B Computer.2On your desktop, select Start > Settings > Control Panel, double-click Folder Options, then click the View tab. Beneath “Hidden files and folders,” check Show hidden files and folders, then click OK to close.3Using the Microsoft ActiveSync application on your desktop, click Explore to access the Flash File Store folder on your CN2B Computer and locate the “registry” file. Copy this file, then paste it in a temporary location on your desktop.
Chapter 3 — Installing Applications82 CN2B Mobile Computer User’s Manual4Remove the CN2B Computer from the cradle, and put another CN2B Computer in its place. The ActiveSync application on your desktop should connect to the new unit. 5Follow the instructions for “Deleting the Old Registry File” on page 79, put the new registry file in the root of the Flash File Store folder on the new CN2B Computer, enable the registry save flag via the Utilities applet, perform a warm-boot. and make sure these settings are saved.Updating the System SoftwareYou can use the Intermec Recovery CD to reinstall or update the operating system software on the CN2B Computer. For more information, contact your Intermec representative.Migrating from Another ComputerAs you migrate from another mobile computer to a CN2B Computer, you need to consider the following: When converting an application to run on the CN2B Computer, most APIs should work without changes. Below are a few exceptions:• The other computer may use the “\Storage Card” folder for nonvolatile storage. You may need to change the application to store data onto the “SDMMC Disk” folder instead of the “\Storage Card” folder if a Secure Digital storage card is present in the system.• If the application uses the RegFlushKey() API, it must first verify that the proper media is available in the system.• Some WAN radio options have changed. Review the WAN radio infor-mation in Chapter 4, “Network Support” to determine if any changes are required in your application.• Keyboard remapping is available on the CN2B Computer should you need to map these keys like that of the original computer (see page 104).• Special Resource Kits are not needed to compile applications for the Xscale processor. Targeting the SA1110 processor creates applications that run on the CN2B Computer.
Chapter 3 — Installing ApplicationsCN2B Mobile Computer User’s Manual 83Installing Cabinet FilesCAB files (short form of “cabinet” files) are compressed folders as defined by Microsoft. A “cabinet” file is a single file, usually suffixed with .CAB, that stores compressed files in a file library. A compressed file can be spread over several cabinet files. During installation, the setup application decom-presses the files stored in a cabinet and copies them to the user’s system.For the CN2B Computer, CAB files register DLLs, create shortcuts, mod-ify registry entries, and run custom setup programs. Tap a CAB file to extract that file or place the CAB file on one of the approved storage devices in the “\CabFiles” folder, then perform a warm-boot on the CN2B Com-puter. There are two methods available to extract a CAB file:• Tap a CAB file to extract it. With this method, the CAB file is automat-ically deleted when the extraction process is successful, unless the CAB file is set with the read-only attribute.• Use AUTOCAB to extract all files when a cold-boot is performed on the CN2B Computer. See the Software Tools User’s Manual for information.

Chapter 4 — Network Support100 CN2B Mobile Computer User’s ManualAutoIP/DHCPAutomatic Private IP Addressing (AutoIP) is enabled by default in Win-dows Mobile 2003. To remain compatible with other versions of Pocket PC, this setting needs to be enabled. You can configure the registry settings in HKEY_LOCAL_MACHINE\Comm\NETWLAN1\TcpIp to set the required AutoIP/DHCP behavior.AutoInterval, AutoMask, AutoSubnet, AutoIP, and AutoSeed are other registry keys that can modify the behavior of AutoIP. You can find the appropriate settings and behavior of each of these keys in Microsoft Help.When a TCP/IP client cannot find a DHCP server, it generates an AutoIP address from the 169.254.xxx.xxx block. The client then tries to check for a DHCP server every 15 seconds and if a DHCP server is found, the client drops the AutoIP address and uses the address from the DHCP server.In the MSDN Windows CE documentation available out on the Microsoft Developer Network web site (www.msdn.com), see “Automatic Client Con-figuration” for more information on AutoIP.To disable AutoIP, set the AutoCfg registry entry to “0.” If a DHCP server cannot be found, instead of using AutoIP, the system will display the “Unable to obtain a server assigned IP address” message.Wide Area NetworksThe CN2B Computer does not support wide area networks.Note: If you try to disable AutoIP using a CAB file to set the registry value for AutoIP, remember to set the EnableDHCP value to “1” to keep DHCP enabled.Note: For more attempts a DHCP client makes to get a DHCP address, use the DhcpRetryDialogue and DhcpMaxRetry registry settings.Note: Change the AutoInterval registry key value to make the client retry more often to obtain a DHCP address.

SNMP Configuration on the Mobile ComputerIn short, SNMP is an application-layer protocol that uses the exchange of management information between network devices. The CN2B Computer is such an SNMP-enabled device. Use SNMP to control and configure the CN2B Computer anywhere on an SNMP-enabled network.The CN2B Computer supports four proprietary Management Information Bases (MIBs) and Intermec Technologies provides SNMP support for MIB-II through seven read-only MIB-II (RFC1213-MIB) Object Identifi-ers (OIDs).Management Information BaseThe Management Information Base is a database that contains information about the elements to be managed. The information identifies the manage-ment element and specifies its type and access mode (Read-Only, Read-Write). MIBs are written in ASN.1 (Abstract Syntax Notation.1) — a machine independent data definition language. Note: Elements to manage are represented by objects. The MIB is a structured collection of such objects. Tap Start > Settings > the System tab > the Intermec Settings icon, then tap to expand the SmartSystems Information option.Note: You can only query these seven OIDs through an SNMP manage-ment station.
Chapter 4 — Network Support110 CN2B Mobile Computer User’s ManualYou will find the following MIB files either in the CN2B Management Tools or on the web via www.intermec.com:•INTERMEC.MIBDefines the root of the Intermec MIB tree.•ITCADC.MIBDefines objects for Automated Data Collection (ADC).•ITCSNMP.MIBDefines objects for Intermec SNMP parameters and security methods, such as an SNMP security IP address.•ITCTERMINAL.MIBDefines objects for parameters, such as key clicks.Object IdentifiersEach object has a unique identifier called an OID, which consist of a sequence of integer values represented in dot notation. Objects are stored in a tree structure and OIDs are assigned based on the position of the object in the tree. For example, the internet OID is equal to 1.3.6.1. Seven MIB OIDs are shown in the following table:MIB Object IdentifiersMIB-II Item OID Group or Table DescriptionifNumber 1.3.6.1.2.1.2.1.0 Interfaces Group Indicates the number of adapters present in the system. For the CN2B Computer, if one adapter is present in the system, then ifNumber = 1 and ifIndex = 1.ifIndex 1.3.6.1.2.1.2.2.1.1.ifIndex Interfaces Table (ifTable) A unique value for each interface. The value ranges between 1 and the value of ifNumber.ifDescr 1.3.6.1.2.1.2.2.1.2.ifIndex Interfaces Table (ifTable) A textual string containing infor-mation about the interface.ifType 1.3.6.1.2.1.2.2.1.3.ifIndex Interfaces Table (ifTable) An integer containing informa-tion about the type of the inter-face.

Chapter 4 — Network SupportCN2B Mobile Computer User’s Manual 111Configuring with SNMPThe community string allows an SNMP manager to manage the CN2B Computer with a specified privilege level. The default read-only commu-nity string is “public” and “private” is the default read/write community string. See the specific configuration parameter to find its OID. To config-ure the CN2B Computers using SNMP:1Configure CN2B Computers for RF or Ethernet communications.2Determine the OID (Object Identifier) for the parameter to change. The Intermec base OID is 1.3.6.1.4.1.1963.3Use your SNMP management station to get and set variables that are defined in the Intermec MIBs. You can set the traps, identification, or security configuration parameters for SNMP. See Appendix A, “Config-urable Settings” to learn more about these parameters.

Chapter 5 — Printer Support114 CN2B Mobile Computer User’s ManualPrinting ASCIIThe following methods for printing using Pocket PC at this time is as fol-lows:• Add port drivers to print ASCII directly to the port.• Use LinePrinter ActiveX Control from the Printing Resource Kit via the Intermec Developer Library (IDL) available as a download from the Intermec webs site at www.intermec.com. Contact your Intermec repre-sentative for more information.• Via wireless printing - see the Wireless Printing Development Guide for more information.Directly to a PortPrinting directly to the port sends RAW data to the printer. The format of this data depends upon your application and the printer capabilities.You must understand the printer commands available for your specific printer. Generally, applications just send raw ASCII text to the printer. Since you are sending data to the printer from your application directly to the port you are in complete control of the printers operations. This allows you to do line printing (print one line at a time) rather than the page format printing offered by the GDI approach. It is also much faster since data does not have to be converted from one graphics format to the other (display to printer). Most Intermec printers use Epson Escape Sequences to control print format operations.These commands are available in documentation you receive with your printers or from technical support. Win32 APIs are required to print directly to the port.Directly to a Generic Serial PortTo print directly to a generic serial port printer (non-Intermec printers):• Use CreateFile() to open ports — COM1 can open on most devices.• Use WriteFile() to send data directly to the printer.• Use CloseHandle() when you are finished printing to close the port.NPCP Printer DriverThe NPCP printer communications driver (NPCPPORT.DLL) is a Stream Device Driver built into the operating system. The driver supports only NPCP communications to and from the 6820 printers over a selected serial port.All applications use WIN32 API functions to access the drivers. Basic oper-ations are easily implemented by applications through the CreateFile(),
Chapter 5 — Printer SupportCN2B Mobile Computer User’s Manual 115WriteFile(), ReadFile(), DeviceIOControl(), and CloseHandle() Win32 APIs.Operations to upgrade printer modules, perform printer diagnostics, and get printer configuration are performed largely via DeviceIOControl() functions.About NPCPNPCP (Norand® Portable Communications Protocol) is a proprietary pro-tocol that provides session, network, and datalink services for Intermec mobile computers in the Intermec LAN environment used with printers and data communications.NPCP Driver Installation and RemovalUse LPT9: for the NPCP printer device and COM1 for the last parameter. COM1 is the connection available via the CN2B Computer.Applications use the RegisterDevice() function to install the driver. Dereg-isterDevice() uninstalls the device driver and frees memory space when the driver is not required. Use the HANDLE returned by RegisterDevice() as the parameter to DeregisterDevice().Use the RegisterDevice() function call as demonstrated below. Specify the full path name to the driver starting at the root for the RegisterDevice() function to work properly. The last parameter to RegisterDevice() is a DWORD that represents the name of the port for the NPCP stream driver to use. Build this parameter on the stack if it is not to be paged out during the call. The first parameter “LPT” (Device Name) and the second parame-ter “9” (index), indicate the name of the registered device, such as LPT9. This is used in the CreateFile() function call.Install(){HANDLE hDevice;TCHAR port[6];port[0] = TCHAR(‘C’);port[1] = TCHAR(‘O’);port[2] = TCHAR(‘M’);port[3] = TCHAR(‘1’);port[4] = TCHAR(‘:’);port[5] = TCHAR(0);hDevice = RegisterDevice ( (TEXT(”LPT”), 9, TEXT(“\\STORAGE CARD\\WINDOWS\\NPCPPORT.dll”), (DWORD)port);}Opening the NPCP DriverThe application opens the NPCP driver by using the CreateFile() function. The call can be implemented as follows. The first parameter “LPT9:” must reflect the device name and index used in the RegisterDevice() function call and will fail for any of the following reasons:
Chapter 5 — Printer Support116 CN2B Mobile Computer User’s ManualhFile = CreateFile(_T(”LPT9:”), GENERIC_WRITE | GENERIC_READ, 0, NULL, OPEN_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);• The port associated with the device during RegisterDevice() is in use.• The NPCP device is already open.• The share mode is not set to zero. The device cannot be shared.• Access permissions are not set to GENERIC_WRITE | GENERIC_READ. Both modes must be specified.Closing the NPCP DriverUsing the CloseHandle() (hFile) function closes the NPCP driver. Where hFile is the handle returned by the CreateFile() function call.• TRUE = the device is successfully closed.• FALSE = an attempt to close NULL HANDLE or an already closed device.Reading from the NPCP DriverReading of the NPCP printers is not supported since all responses from the printer are the result of commands sent to the printer. DeviceIoControl() functions are provided where data is to be received from the printer.Writing to the NPCP DriverAll Print data can be sent to the printer using the WriteFile() function. The print data written to the driver must contain the proper printer commands for formatting. If the function returns FALSE, the NPCP error may be retrieved using IOCTL_NPCP_ERROR. See the description on the next page.NPCP Driver I/O ControlsAn application uses the DeviceIoControl() function to specify an printer operation to perform. Certain I/O controls are required to bind and close communication sessions with the printer, and must be completed before any other commands to the driver can execute properly.The function returns TRUE to indicate the device successfully completed its specified I/O control operation, otherwise it returns FALSE. The follow-ing I/O control codes are defined:#define IOCTL_NPCP_CANCEL CTL_CODE(FILE_DEVICE_SERIAL_PORT,0x400,METHOD_BUFFERED,FILE_ANY_ACCESS)#define IOCTL_NPCP_BIND CTL_CODE(FILE_DEVICE_SERIAL_PORT,0x401,METHOD_BUFFERED,FILE_ANY_ACCESS)#define IOCTL_NPCP_CLOSE CTL_CODE(FILE_DEVICE_SERIAL_PORT,0x402,METHOD_BUFFERED,FILE_ANY_ACCESS)

It flushes the printer buffers and re initializes the printer to its default state. No parameters are required.•IOCTL_NPCP_BINDThis command is required before any data is sent or received by the printer. Once the driver is opened, the application must bind the com-munications session with the printer before any data can be sent or received by the printer. If an error occurs during the bind, the applica-tion may use IOCTL_NPCP_ERROR to get the current extended error code. No parameters are required.•IOCTL_NPCP_CLOSEThis command closes the current session with the printer. This function always returns TRUE. No parameters are required.•IOCTL_NPCP_ERRORThis command returns the extended NPCP error code in PL/N format. The word returned will contain the PL/N compatible error code in the low byte and completion flags in the high byte. If the frame that returned an error was not received correctly by the printer the FRAME_NOT_ACKED bit is set in the high byte. This operation always returns TRUE. An output buffer of at least two bytes is required. See “NPCP Error Codes” on page 118.•IOCTL_NPCP_FLUSHThis command allows the application to poll the printer for errors while the report is completing the print process at the printer. If an error occurs during the polling process, the operation will return FALSE and the application can get the extended error code by using IOCTL_NPCP_ERROR. No parameters are required.NPCP Printer CommunicationsAll NPCP printer communications should be based on the following flow:1Use CreateFile(); to open the printer driver.2Use IOCTL_NPCP_BIND to bind a session with the printer; IOCTL_NPCP_ERROR to check for errors on the bind to ensure suc-cess; and IOCTL_NPCP_CANCEL to cancel any outstanding print jobs.
Chapter 5 — Printer Support118 CN2B Mobile Computer User’s Manual3Use IOCTL_NPCP_FLUSH to poll the printer to free up printer buffer resources. Use IOCTL_NPCP_FLUSH to poll the printer’s status. If an error is reported by the IOCTL, then use IOCTL_NPCP_ERROR to get the error and determine the correct recovery procedure.4Use WriteFile(); to write your data to the printer. Check for errors and that all data were written. Use IOCTL_NPCP_ERROR to get the extended error. If the error is critical in nature, use IOCTL_NPCP_CLOSE, followed by CloseFile(), to end the communi-cations session. Start a new session, beginning with step 1 to ensure proper printing. For noncritical errors display the error and retry the operation.5After all data is sent to the printer, ensure that the printer continues to print the report properly by polling the printer’s status. Use IOCTL_NPCP_FLUSH to poll the printer’s status. If an error is reported by the IOCTL, then use IOCTL_NPCP_ERROR to get the error and determine the correct recovery procedure.Sample CodeSee sample code in the “\CN2B Dev Tools\Installable Drivers\Port Driv-ers\Npcp\NPCPPrint\” directory for more details on printing, printer com-munications and error code handling.NPCP Error CodesCall the IOCTL_NPCP_ERROR I/O control function to receive PL/N compatible error codes.

Basic opera-tions are easily implemented by applications through the CreateFile(), WriteFile(), DeviceIOControl() and CloseHandle() Win32 APIs.The driver supports communications to PB20, PB40, and PB42 printers over a selected serial port.DTR Driver Installation and RemovalYour application must install the device driver by using the RegisterDe-vice() function. The driver name is ONEIL.DLL. We recommend that you use “DTR” for the Device Name parameter, “1” for the Device Driver index parameter, and use any of the following strings for the last parameter:• NULL (==0) Defaults to COM1 @ 9600• “COM1” only COM port specified defaults to 9600• “COM1:9600” sets to COM port and specified bit rate• “COM1:19200” sets to COM port and specified bit rateUse the HANDLE returned by RegisterDevice() as the parameter to Dereg-isterDevice(). The correct usage of the RegisterDevice() function call is demonstrated below. You may use DeregisterDevice() to uninstall the driver.Install(){HANDLE hDevice;TCHAR port[6];port[0] = TCHAR(‘C’);port[1] = TCHAR(‘O’);port[2] = TCHAR(‘M’);port[3] = TCHAR(‘1’);port[4] = TCHAR(‘:’);port[5] = TCHAR(0);hDevice = RegisterDevice ( (TEXT(”DTR”), 1, TEXT(”\\WINDOWS\\ONEIL.DLL”),(DWORD)port);}
Chapter 5 — Printer Support120 CN2B Mobile Computer User’s ManualOpening the DTR DriverThe application opens the DTR driver by using the CreateFile() function. The call can be implemented as follows:hFile = CreateFile(_T(”DTR1:”), GENERIC_WRITE, 0, NULL, OPEN_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);The first parameter “DTR1:” must reflect the device name and index used in the RegisterDevice() function call.The function call will fail for any of the following reasons:• The port associated with the device during RegisterDevice() is currently in use.• The DTR device is already open.• The share mode is not set to zero. The device cannot be shared.• Access permissions are not set to GENERIC_WRITE.Closing the DTR DriverUsing the CloseHandle() (hFile) function closes the DTR driver. Where hFile is the handle returned by the CreateFile() function call.• TRUE indicates the device is successfully closed.• FALSE indicates an attempt to close a NULL HANDLE or an already closed device.Writing to the DTR DriverYou can use the WriteFile() function to send all Print data to the printer. The print data being written must contain the proper formatting printer commands.DTR Printer CommunicationsAll DTR printer communications should be based on the following flow:1Use CreateFile() to open the printer driver.2Use WriteFile() to write your data to the printer. Check for errors and that all data were written.3Use CloseHandle() to close the driver.
