Problem with Print Queue


I have SCADA in QNX 4.25 ,Watom C & Photon , everyday after each
process , i have to take the print of report, i am maintaing the print queue,
but some time printer doesn’t take print and become hang then only i have to Restart the PC. Is there any function that can be used to clean up the print queue (//0/PRNTQ).

One thing is that i have not installed the printer(DOT Matrix),only i m dumping by system command.
If anyone can help pls reply…
