You should not specify a width of more than 80 characters for a

letter-quality printer that uses 8 1/2-inch by 11-inch paper. If you specify a

width that is greater than 80 characters on a printer, the page prints in

landscape mode.

For high-resolution laser-type printers, the line length and page width

parameters are py and px, which specify the number of pixels along the y-

and x-coordinate planes of the printer output image area. Some printers

can operate in either constant-width or imaging modes, so you must specify

both sets of parameters. For example:

px#60

py#80

Refer to your printer’s manual for its output characteristics.

10.8 Troubleshooting

This section provides a checklist for diagnosing printer problems. It also

describes how print errors are logged in the /usr/adm/lperr ﬁle,

providing this feature is speciﬁed in the /etc/printcap ﬁle.

10.8.1 Installation and Routine Operations

If a problem occurs on an existing printer or when adding a printer to a

system, diagnose the problem as follows:

• Verify that the printer hardware is correctly installed and operating as

expected. Most printers have internal test and print test options.

• Ensure that the correct settings are recorded in the /etc/printcap

ﬁle. Refer to Section 10.7.3.

• Ensure that the printer daemon is present by using the following

command:

# ps agx |grep /usr/sbin/lpd

If the daemon is not running, restart it by using the following

commands:

# rm -f /dev/printer /var/spool/lpd.lock

# /usr/lbin/lpd -l

The ﬁrst command removes the /dev/printer and

/var/spool/lpd.lock ﬁles. In the second command, the −l option

causes the daemon to log requests from the network. This ﬂag is useful

for debugging problems with remote printers.
