Print queue status conditions
Some of the status conditions that a print queue can have are:
DEV_BUSY
Indicates that:
• More than one queue is defined to a printer device ( lp0 ) and another
queue is currently using the printer device.
• qdaemon attempted to use the printer port device ( lp0 ), but another
application is currently using that printer device
To recover from a DEV_BUSY, wait until the queue or application has
released the printer device or cancel the job or process that is using the
printer port.
DEV_WAIT Indicates that the queue is waiting on the printer because the printer is
offline, out of paper, jammed, or the cable is loose, bad, or wired
incorrectly.
To recover from a DEV_WAIT, correct the problem that caused it to wait. It
may be easier for diagnostic testing to use the enq command to move all
queued jobs from the DEV_WAIT queue to another queue that is either
printing or is DOWN. After the problem is corrected, you can move any
unprinted job back to the original queue.
DOWN A queue will usually go into a DOWN state after it has been in the
DEV_WAIT state. This situation occurs when the printer device driver
cannot tell if the printer is there due to absence of correct signaling.
However, some printers may not have the capability to signal the queuing
system that it is offline, and instead signals that it is off. If the printer device
signals or appears to be off, the queue will go into the DOWN state.
To recover from a DOWN state, correct the problem that has brought the
queue down and have the system administrator bring the queue back up.
The queue must be manually brought up before it can be used again.
HELD Specifies that a print job is held. The print job will not be processed by the
spooler until it is released.
QUEUED Specifies that a print file is queued and is waiting in line to be printed.
READY Specifies that everything involved with the queue is ready to queue and
print a job.
RUNNING Specifies that a print file is printing.
