CHAPTER 13 TROUBLESHOOTING
13-7
UNIX Troubleshooting
1. Make sure that the /etc/printcap file (if applicable) is typed in correctly.
In particular, look for missing ":" and "\" characters, because a small
error anywhere in the file can have major consequences. Also check the
/usr/spool directory to make sure that you have created a valid spool
directory.
2. If you are using a Linux operating system, the X-Window Print tool
program that is included with Linux may not properly configure the
etc/printcap file for lpd operation, then you might also edit the
etc/printcap file and change the following line in the entry for the printer.
if
:lp = /dev/null: \
then to
:lp = :\
3. If you are using a Berkeley-based UNIX, make sure that the daemon is
started on Berkeley based systems with the command lpc start printer,
where printer is the name of the local print queue.
4. If you are using an AT&T-based UNIX, make sure the printer is enabled
(enable printer, where printer is the name of the local print queue).
5. Make sure that the lpr/lpd remote line printer service are running on the
host computer (refer to your host computer documentation for
information on how to do this).
