FUNCTIONAL DESCRIPTION

The console is capable of printing up to 30
characters per second and provides 132 print
positions for the 64-character ASCII code set.
Each character printed by the impact print
head is formed by a 7 by 9 dot matrix.
The device can accommodate variable fan-fold
paper forms in widths of from 4 to 15 inches and
can print 1 original and up to 4 copies. Horizontal
spacing is 10 characters per inch; vertical spacing
is 6 lines per inch.
The device is intended as the primary input/
output device for communication to and from the
system.
