PS-4A AND PS-4E: PARALLEL PRINTER
INTERFACE
Parallel ports on the PS-4A and PS-4E have DB-25 female
connectors. A DB- 25 male-to-Centronics cable is required
between each printer having a Centronics connector and the
BayTech print server (same as IBM PC to Centronics cable).
The pin layout for the DB-25 connector is similar to IBM PC parallel
connector and uses the following signals:
