lpadmin(1M) and lpfence(1M) for additional details.
Printer Logging
Every spooling system request is logged in a log file located in /usr/spool/lp/log.
The file contains a record of each spooling system request, including request ID, user
name, printer name, time, error messages, and reprints due to failure.
Summary of Line Printer Spooling System Commands
These are the commands associated with the line printer spooling system and a summary
of what they do. See their respective manpages for complete details. In addition to
these commands, most features of the spooling system can be controlled using one of
the system administration tools such as the System Management Homepage.
lpadmin lpadmin allows you to:
Add/remove printers to/from the spooler
Define printer classes
Set the default priority for a printer
lpsched lpsched (the scheduler) is the heart of the line printer spooling system.
When it is running, the line printer spooling system is considered to be
running; when it is not running the line printer spooling system is
considered to be not running. The lpsched command starts the scheduler
running.
lpshut Performing the opposite function of the lpsched command is the lpshut
command. lpshut stops the scheduler and therefore stops all printing
on all printers.
lp The lp command submits a new print request to the line printer spooling
system. When you want to print something from a shell environment (from
a command line), use the lp command.
lpstat The lpstat command reports the current status of the scheduler
(“running” or “stopped”), whether or not a print queue (printer or class
queue) is currently accepting new print requests, whether or not printers
in the spooler are currently enabled, and which print requests are queued
up or printing on each print queue.
lpmove The lpmove command moves a print request from one print queue to
another or to move all queued print requests on one queue to a different
queue. The lpmove command can only be used when the scheduler is not
running.
lpalt The lpalt command allows you to change the attributes of specified print
requests. Using lpalt you can:
