Guide to Printers and Printing
Queue Device The queue device is the line or list of items in the /etc/qconfig file that
normally follows the local queue. It specifies the /dev file (printer
device) to print to and the backend to use. Following is a sample listing:
lp0:
file = /dev/lp0
header = never
trailer = never
access = both
backend = /usr/lib/lpd/piobe
There can be more than one queue device associated with a single
queue.
Adding a printer through the Web-based System Manager wsm
devices fast path creates a standard queue device entry to an existing
queue.
Note: There will not be a file entry in the /etc/qconfig file when you
are using a remote printer. The queue directs the file to the server.
qdaemon
The qdaemon is a process that runs in the background. When you turn
the system on, the startsrc command starts the qdaemon. startsrc is
a command to the srcmstr daemon that is started from /etc/inittab.
The qdaemon keeps track of the print requests in the
/var/spool/lpd/qdir directory and ensures that the jobs are sent to the
proper printer at the proper time. It also keeps track of the status of the
printers and stores printer usage data for system accounting purposes
(for example, lpstat and enq –A commands). This information is held in
the /var/spool/lpd/stat directory.
If the qdaemon is stopped, it will be restarted by the srcmstr.
Note: Do not stop the srcmstr process; it controls other daemons
running on your system.
