Installing the Printer and Drivers
Using printcap to configure a Unix workstation for the printer's
serial port
The printcap file configures the workstation's lpr queues. The file is usually found in
the workstation's /etc directory. The printer's rear panel switch settings should all be
down. Use a null modem cable, since the printer is set up as a DTE device. For this
example, the printer's serial port settings are as follows:
Speed: 9600
Flagging: Software (XON/XOFF)
Data Bits: 8
Parity: Ignore
To set up a printcap entry, perform the following steps:
1.
Make a backup copy of the /etc/printcap file.
2.
Add to the printcap file a new print queue name and set the port parameters
as needed. Add the following to the printcap file:
px:\
:br#9600:rw:\
:fc#00000374:fs#00000003:\
:xc#0:xs#0040060:\
:mx#0:sf:sh:\
:sd=/var/spool/px:\
:if=/var/spool/px/if:\
:lp=/dev/ttya:
px may be changed to whatever unique printer name you choose. The device
driver name in lp may be different depending upon which serial port the
printer is connected to and the device driver naming scheme for the
workstation.
3.
Create a directory called /var/spool/px and create a file in the directory called
if. The content of the file should look like this:
#!/bin/sh
/bin/cat
4.
Give the if file executable permission:
chmod +x if
If communication to the serial port uses 7 data bits, the value for xs changes
as follows. All other setup parameters remain the same.
