It could be because: (a) there are jobs (maybe yours) stuck/clogging up the print queue, (b) your print job is too large, or (c) there is some problem with the printer: ie, paper jam, out of paper.

1. How to check the status of the print queues and remove your stuck jobs.

Check to see if there are jobs stuck in the print queue. You can view the queue by using the lpq command on a UNIX machine. To specify the printer you must use the -P option to the lpq command. For example to look at the queue for the cadps1 printer you would type lpq -Pcadps1. This command shows the filename, owner, and a job number. You can remove your job by referring to the job number using the lprm command. Note: You cannot remove jobs other than those owned by you. For example you might type lpq to get the job number of the job in question and then once you have that, use lprm job# where job# is some numeric value. Once again you need to specify the printer with the -P option, so to remove a job from the cadps1 queue, use lprm -Pcadps1 job#. You may want to read the UNIX manual page for these commands. To do so type man lprm, etc. If you see that there are jobs that are stuck in the queue that you are not able to remove because they belong to someone else, then either let the monitor on duty know so that he or she can remove it, or if it is during normal working hours, you can send mail to This e-mail address is being protected from spambots, you need JavaScript enabled to view it .

2. Your print job may be too large.

You may need to split your print job up into smaller units.

3. There is a problem with the printer.

Occasionally a problem happens with the printer such as a paper jam, low toner, or out of paper. When this is case then again, either let the monitor on duty know so that he or she can remove it, or if it is during normal working hours, you can send mail to This e-mail address is being protected from spambots, you need JavaScript enabled to view it .
