STANDARD FEATURES

OPTIONAL FEATURES

•

•

VERTICAL FORMAT UNIT - paper movement
controlled by programmed paper tape in a vertical
format control unit directly linked to a gear train
vvhich drives the paper feed tractors.

•

AUTcftvlATIC MOTOR CONTROL - the main drive
motor is automatically turned off when no characters
have been received by the printer for 7 seconds.

PARALLEL DATA INPUT - transmission rate of up
to 75,000 characters per second (burst).

• STROBED !NPUT - prevents invalid data by refusing
inputs until receipt of last character is acknowledged.
•

EASY TO READ - 54 well-formed characters in a
9-by-7 dot matrix that is equivalent to 1 O-point type.

INTRODUCTION
• VERTICAL/HORIZONTAL REGISTRATION - vertical spacing is fixed at 5 lines per inch; horizontal
spacing is fixed at 10 characters per inch.
• STANDARD OUTPUT AND SPECIAL EFFECTS standard 54-character USASCII code set; elongated
characters on a character-by-character basis, initiated
by software.
•

LOW NOISE LEVEL conditions, below 55 dB.

Now, hear this! - to all microprocessor users who
require a low-cost, medium-speed, impact printer with
system interface. The IMP-00/812(E) is the printer you
want for IMP and PACE Prototyping Systems. Using
appropriate software, this printer provides an output of
100 characters per second at a maximum line width of
80 characters; the characters are imprinted with a
standard 9-bt-7 dot matrix.
For 80-character lines, the average speed is 50 lines per
minute; for lines with less than 30 characters, speeds in
excess of 150 lines per minute are obtainable.
Special paper is not required, and one original and one to
four carbon copies, all very clean and legible, can be
produced. The paper is sprocket-fed and can be varied in
width to a maximum of 9Y:! inches. As an option, special
character sets can be implemented, and, under software
direction, elongated boldface characters can also be
printed. The printer is completely self-contained.
