W resistance.
The DC1/DC3 code are valid
only when this signal is
high. (This signal can be fixed
low by changing a DIP switch,
jumper, or SelecType setting on
the printer.) The printer
monitors this signal, so this
signal’s function depends on
the printer’s specifications.
Note
•
The column heading Direction refers to the direction
of signal flow as viewed from the printer.
•
All interface conditions are based on TTL level. Both
the rise and fall of each signal must be less than 0.2
µseconds.
