Introduction

Congratulations for selecting the TRS-80 DWP-510. We think it's one of the best medium-cost, high-quality

printers available for microcomputers and it should provide you with years of reliable service.

With asimple change of print wheels, the DWP-5 10 can provide print-outs in avariety of font styles.

Other special features of the DWP-510 include:

®Selectable print pitch (characters per inch). The pitch can be specified via the DWP-510 front panel switches

or, for maximum flexibility, via program control.

•Tractor Feed (optional/extra) paper handling for fanfold paper, or Friction Feed (standard) paper handling for

single-sheet or fanfold paper.

®ASelf-Test feature that lets you see if the Printer is operating properly before you begin printing.

•An Out-of-Ribbon Sensor that automatically stops printing when the ribbon runs out.

•Special Line Feeds (1/48", Reverse, etc.) for special printing applications.

and much more!

This manual will:

®Describe the DWP-5 10 to you.

®Show you how to set it up.

•Describe how to use the Printer in avariety of printing applications.

1/ Description of the DWP-510

When you unpack the DWP-5 10, be sure the package contains a:

®DWP-510

•Power Cord

®Print Wheel

•Ribbon Cartridge

Be sure to unpack the cushions found on the inside of the Printer. You'll have to grasp the front cover with both

hands and gently lift it up to gain access to the inside of the Printer.

It's important to become familiar with the Printer before you begin using it. Study the following section carefully

before setting up and using the DWP-5 10.

2/ Setting Up the

When setting up the DWP-510, always be sure you pick alevel, sturdy location with plenty of room for easy

paper flow.

Print Wheel Installation/Removal

The DWP-510 package includes aCourier 10 print wheel which you will need to install before printing. Radio

Shack carries anumber of different print wheels for printing different font styles. These include:

•Courier (10 pitch) (26-1430)

•Prestige Elite (12pitch) (26-1431)

•Madeleine (Proportional Space) (26-1432)

®Cubic (Proportional Space) (26-1433)

•Tile Italic (12 pitch) (26-1434)

®OCR-B (26-1435)

•Letter Gothic (12 pitch) (26-1436)

•Cubic 15 (26-1438)

•Bold Proportional Space (26-1439)

•Scientific A/N (26-1486)

•Pica (10 pitch) (26-1290)

•Narrator (26- 1291)

•OCR-A (26-1292)

•Elite (12 pitch) (26-1293)

If these font styles don't fit your immediate printing needs, be sure to check with your local Radio Shack Com-

puter Center or store since we are continually making more font styles available.

To Install the Print Wheel:

1. Remove the ribbon cartridge from the carriage by gently lifting the ribbon cartridge straight up.

2. Grasp the two green handles (which are closest to the platen) between your thumb and forefinger and gently tilt

the carriage toward you.

3. Hold the print wheel by the green hub. When the print wheel is properly installed, the hub will be toward the

paper.

4. Position the red dot (on the back of the print wheel, opposite the hub) so that it corresponds to and fits into the

open notch on the carriage. (Match the red on both the hub and the notch.)

5. Push down on the hub until the wheel clicks into place. The green hub should be all the way down.

6. Grasp the two green handles (which are closest to the platen) between your thumb and forefinger and gently tilt

the carriage away from you; firmly press the carriage down into its original position.

7. Replace or reinstall the ribbon cartridge.

To Remove the Print Wheel:

1. Remove the ribbon cartridge.

2. Tilt the carriage back as described above.

3. Grasp the green hub of the print wheel and pull up. For easier removal, gently twist the wheel back and forth

while pulling it up.

Ribbon Cartridge Installation/Removal

Radio Shack carries two ribbon cartridges for the DWP-510— ahigh-quality carbon ribbon (26-1419) and along

life nylon ribbon (26-1449). No matter which ribbon you choose, you'll find that they're both easy to install and

remove.

Note: When the carbon ribbon (26-1419) runs out, the printer detects the end of the ribbon and stops printing.

The nylon ribbon (26-1449) is an endless loop, so this will not happen.

To Install aRibbon Cartridge:

Before installing the cartridge, remove all slack in the ribbon by turning the green knob on the cartridge in the

direction indicated by the arrow (clockwise).

2. Position the cartridge so that the ribbon slides into position between the print wheel and the plastic card guide;

the tabs on the cartridge should line up with the green claws on the carriage.

3. Press down on the cartridge and snap it into place.

4. Turn the ribbon feed knob 1/4 to 1/2 turn clockwise until the cartridge locks down.

To Remove aRibbon Cartridge:

Gently press the green carriage claws away from the cartridge tabs.

2. Lift up on the cartridge. Be careful not to catch the ribbon on the print wheel.

Paper Loading

You can use either fanfold computer paper or single-sheet typewriter paper with the DWP-510.

If you're using fanfold paper, you'll find it most efficient to use the optional/extra DWP-510 Bidirectional Trac-

tor Feed unit (26-1447).

Friction Feed Paper Loading

Gently pull the paper bail away from the platen.

2. Set the platen pressure lever toward the rear side of the Printer (pressure ON).

3. Insert the paper behind the platen and turn the platen manually(turn the paper advance knob) so that the paper

advances past the card guide.

4. Set the platen pressure lever toward the front of the Printer (pressure OFF) so that the paper can move freely

back and forth.

5. Align and position the paper at the left margin.

6. Hold the paper in position and move the platen pressure lever back toward the rear side of the Printer (pres-

sure ON). The paper will no longer move freely.

7. Lower the paper bail so that it is against the paper.

8. Position the paper manually to the first line of printing by turning the paper advance knob.

Note: Be sure the Copy Control Lever is set to 1unless you're using multiple form paper. If the Printer runs out of

paper, no out of paper signal will be sent to the computer; the Printer will continue printing on the platen.

If this happens, immediately turn the ON-LINE/OFF-LINE switch to OFF-LINE; after loading more pa-

per, return this switch to ON-LINE.

Connecting the DWP-510 to aPower Source

Always be sure the DWP-510 is connected to a grounded wall outlet or grounded approved power strip, such as

Radio Shack's Plug-In Power Strip (6 1-26 19) or the Automatic Power Controller, Model SW-30 1(26- 1429).

Always use the supplied cord when connecting the DWP-5 1to apower source.

1. Plug the female end of the cord into the connector on the rear side of the Printer.

2. Connect the other end of the cord into an approved power source.

Connecting the DWP-510 to aXMS-80

The DWP-510 can be used with any TRS-80 Computer or Data Terminal that has parallel interface capabilities.

This includes the:

•Model I

•Model II

•Model III

•Model 4

•Model 12

•Model 16

•Model 100

•Model 2000

•DT-1 Data Terminal

However, before connecting the Printer to the TRS-80, be sure you have the correct cable. Table 1summarizes

the appropriate Radio Shack cables; Table 2briefly describes the location points on the TRS-80s.

3/ Using the DWP-510

Before using the DWP-5 10, you should perform the Self-Test to ensure that the Printer is operating properly.

Before running the Self-Test, however, you should load wide paper (15") into the Printer because Self-Test per-

forms printing across the full length of the platen. To run the Self-Test;

Set the Printer power ON/OFF switch to ON.

2. Set the ON-LINE/OFF-LINE switch to OFF-LINE.

3. Set the TEST switch to ON.

To end the Self-Test, set the TEST switch to OFF.

Setting the Pitch Switch

Be sure to set the PITCH switch (on the front panel) to the position that corresponds with the print wheel you are

using. If you are using aCourier 10 print wheel, for example, set the Switch to 10; if you're using aMadeleine

Proportional Space wheel, set the switch to PS.

Do not accidentally bump the PITCH switch during printing. Unless you change the pitch via software, the cur-

rent switch setting remains in effect. (Once you change the pitch via software, you must turn the Printer power

OFF to use the front panel switch.)

Setting the New Line Switch

Inside the front panel (right side of the frame) is aswitch to select Carriage Return with Line Feed or Carriage Re-

turn only when the Printer receives code 13, the Carriage Return code (see next section ).

Normally, you'll leave this switch in the CR+LF position. For some applications (like when you are using the

Printer with an IBM PC), set it to CR ONLY

You can also select CR +LF or CR only via software (27 21/27 22 code sequence). However, once you change

this function via software, you must turn the Printer power OFF to use this switch.

Control Codes and the DWP-510

Before using the DWP-5 10, consider how the TRS-80 communicates with the Printer.

All information is sent to the Printer as numbers between and 255 decimal (00-FF for you hexadecimal fans).

The printer interprets these numbers according to the American Standard Code for Information Interchange,

commonly referred to as the ASCII code. (See Appendix Afor alist of ASCII codes.) Most numbers (or codes)

are printed as letters, numbers, or symbols. However, the numbers 0-31, as well as some special sequences of

code numbers, are used to control various functions of the Printer. These Control Codes allow you to control line

feeds, backspacing, underlining, etc.

13 -

Sending Control Codes from BASIC

Some Printer functions are activated by asingle code, but many require asequence of two or more codes. Most

multiple-code sequences begin with decimal 27 (referred to as the ESCape code). The ESC code notifies the

Printer that aspecial sequence is on its way. The next code(s) sent determines which Printer function is selected.

In BASIC, use CHR$ ()to send these codes to the Printer.

For instance, set up the DWP-510 as described earlier and enter BASIC in the normal way. Then type the fol-

lowing short program:

10 LPRINT CHR$(15); "UNDERLINE" CHR$(14); "NO UNDERLINE"

and RUN it.

Roll the paper forward and look at the results. The word UNDERLINE was underlined and the words NO

UNDERLINE were not underlined. Why? The codes CHR$(15) and CHR$(14) are the guilty parties. Take a

quick look at Table 3. This chart shows the various code sequences understood by the DWP-5 10.

*Line Feeds may be sent from machine-language programs, but not from BASIC'S LPRINT statement. See

the Technical Information section of your TRS-80 owner's manual for details on sending Line Feeds.

** Normally, CHR$(13) causes aCarriage Return plus aLine Feed. However, after aCHR$(27); CHR$(21) is

sent, aCHR$(13) causes aCarriage Return only; CHR$(27); CHR$(22) causes areturn to normal.

*** See External Program Mode later in this manual.

Note: There are three more control codes that function only when you are using theOptional Auto Sheet Fee-

der. Refer to the Auto Sheet Feeder owner's manual for the specific codes.

LPRINT CHR$(27); CHR$(14)

All subsequent characters will be printed in 12 pitch.

LPRINT CHR$(27); CHR$(17)

All subsequent characters will be printed in Proportional Spacing.

External Program Mode

On some special print wheels, such as the OCR-B 10 and others, you'll need to externally control the:

•Spacing between Proportional Spaced characters

•Amount of ribbon feed.

•Printing impression level.

The print wheels that require external programming will be labeled Require Special Programming on the

packaging material. Each print wheel package will contain external programming code information.

To enter the External Program Mode, send aCHR$(27); CHR$(24). Then send atwo-byte code for each

character or symbol.

•The first byte is the ASCII code for the character.

•The second byte contains the data specifying the printing format (i.e., printing impression level, ribbon feed,

and pitch).

Important Note! This must be done for each character during the External Program Mode or an error will occur.

Table 4describes printing impression levels, Table 5shows Ribbon Feed, and Table 6details spacing between

Proportional Spaced characters. Note that these tables list binary values. You'll need to combine the binary

values and then convert the binary values (using the Base Conversion Chart in your TRS-80 owner's or reference

manual) to adecimal value, then send that decimal value to the Printer with CHR$( ).

For example, in OCR-B, the letter Trequires 1/10" spacing, normal ribbon feed and printing impression level 4.

Looking at Table 6, you'll see the 1/10" spacing is binary 0110. Table 5shows you that normal ribbon feed is

binary 1and Table 4shows that printing impression level 4is binary 100. Adding these values together produces

abinary value of 01 101 100 (01 10 +1+100 =01 101 100). By referring to your Base Conversion Chart in a

TRS-80 owner's or reference manual, you'll see that binary 01 101 100 is equal to decimal 108. Therefore, if you

send aCHR$(84); CHR$(108) to the DWP-510, the letter Twill be printed.

Special Functions

When using the DWP-5 10, you should be aware that there are special functions available.

Auto NL (New Line)

In some cases, the DWP-5 10 will automatically execute aNew Line function (Carriage Return and Line Feed).

These cases include:

•When the DWP-5 10 is set to 10 pitch and the carriage is in the 136th column position.

•When the DWP-510 is set to 12 pitch and the carriage is in the 163rd column position.

•When the DWP-5 10 is set to Proportional Spacing and the carriage moves to within 8units (8/60") of the right

margin.

REMEMBER! The New Line switch can be set to select either Carriage Return with Line Feed or Carriage Re-

turn only. Usually it is set to CR+NL. (when you are using the DWP-510 with an IBM PC, set this switch to CR

ONLY.) Refer to Setting the New Line Switch.

Optimizer

For more efficient printing, the DWP-510 stores certain codes when they are received within 10 milliseconds of

each other. These codes include:

•Space

®Backspace

•Line Feed (including New Line)

•Reverse Line Feed

•Half Line Feed

•Half Reverse Line Feed

These codes are stored until either the character codes or function codes are sent within intervals of 10 msec or

more. When either of these situations occurs, the stored codes are executed one at atime. For example, when 10

Line Feed codes. are entered with less than 10 msec intervals, the DWP-510 will automatically feed 10 lines at

once.

4/ Care and Maintenance

Only the parts marked with green require any normal handling/adjustment. Any other maintenance should be

performed only by aqualified service technician.

Of course, you can and should perform standard cleaning procedures —just as you would with any office type-

writer. Clean the platen, print wheel and other parts with standard typewriter cleaning fluids (use asoft, lint-free

cloth).

Some do's and don'ts to assure maximum performance and reliability from your Printer:

DO DON'T

Plug power cord into 3-wire grounded outlet. Operate Printer in environments of high dust or dirt

content, high temperature or humidity.

Position the Printer on afirm, clean, flat surface.

Place any objects on any part of the Printer (if anything

Use only alint- free cloth to clean the Printer case. falls inside the Printer, turn Printer power off and

Mild detergent solution can be used sparingly. carefully remove the object).

Ensure that all covers are closed and secured before Use alcohol, solvents or harsh cleaning agents on any

operating. part of the Printer.

Turn off power before making any adjustment. Operate Printer without paper (if paper is less than

15" wide take care not to print lines too long for the

paper).

Troubleshooting

If the Printer fails to operate properly, try to solve the problem as follows:

Power lamp does not turn on :

ACheck to see that the AC cord is plugged securely into an appropriate power source.

2. No communication with the TRS-80 :

ACheck to see if the interface cable is properly connected.

BCheck to see if the ON-LINE/OFF-LINE switch is ON-LINE.

3. Printer will not print

AEnsure that the cover is securely closed.

BCheck and change the ribbon, if necessary.

CPerform the Self-Test! operation to ensure that the Printer is internally capable of printing (see page 13).

DEnsure that the print wheel is locked into position.

ECheck to see if anything has fallen into the mechanism that is physically obstructing the carriage move-

ment.

SERVICE POLICY

Radio Shack's nationwide network of service facilities provides quick, conve-

nient, and reliable repair services for all of its computer products, in most

instances. Warranty service will be performed in accordance with Radio

Shack's Limited Warranty. Non-warranty service will be provided at reasonable

parts and labor costs.

Because of the sensitivity of computer equipment, and the problems which can

result from improper servicing, the following limitations also apply to the

services offered by Radio- Shack:

If any of the warranty seals on any Radio Shack computer products are

broken, Radio Shack reserves the right to refuse to service the equipment or

to void any remaining warranty on the equipment.

2. If any Radio Shack computer equipment has been modified so that it is not

within manufacturer's specifications, including, but not limited to, the in-

stallation of any non-Radio Shack parts, components, or replacement

boards, then Radio Shack reserves the right to refuse to service the equip-

ment, void any remaining warranty, remove and replace any non-Radio

Shack part found in the equipment, and perform whatever modifications are

necessary to return the equipment to original factory manufacturer's speci-

fications.

3. The cost for the labor and parts required to return the Radio Shack com-

puter equipment to original manufacturer's specifications will be charged to

the customer in addition to the normal repair charge.
