Printer 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. Sometimes, the jobs have to be removed from the queue before the problem can be corrected.

A queue that is in DEV_WAIT for longer than a defined number of seconds will go into a DOWN state.

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 signallng. However, some printers might 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.
