Radix User's Manual
Radix will report that it has run out of paper by making the
PAPER OUT signal on pin 12 high. This pin can be held low by
turning DIP switch
C-l
off. When the printer is in the on-line state
pin
13
is held high. This signal (SELECTED) tells the computer
that the printer is ready to receive data.
Pins
14, 15,
and 34-36 are not used, while pins
16, 17, 19-30
and 33 are grounded. Pin
18
is connected to
the +
5VDC
supply in
the printer.
Pin 31 can be used to reset the printer. If this signal (RESET)
goes low the printer will reinitialize. Pin 32 is used to report error
conditions in the printer. This signal (ERROR) is high during nor-
mal operation and goes low to report that the printer cannot print
due to an error condition.
