qcan [-X ] [ -x JobNumber ] [ -P Printer ]
The qcan command cancels either a particular job number or all jobs in a print queue.
You can use the Web-based System Manager Printer Queues application (wsm printers fast path) to run this command. You could also use the System Management Interface Tool (SMIT) smit qcan fast path to run this command.
In AIX 4.3.2 and above, qstatus was enhanced to improve the administration of local queues showing duplicate 3-digit job numbers. You can use the -W flag with the enq, qchk, lpstat, and lpq status commands to display more job number digits.
If your queue display shows duplicate 3-digit job numbers, use qchk -W to list job numbers with greater precision. You can then cancel a specific job.
For example, qchk might display job number 123 twice while, qchk -W would display job number 1123 and 2123. If you want to cancel job number 2123, specifying qcan -x 123, causes the qdaemon to cancel the first matching job number it finds in its internal list, which may be 1123. By having the additional information that the -W flag provides, you can cancel a specific job number.
