Automatically cancel problem print jobs

[Nathan Tain]

We have about 50 printers in our office that use CUPS.  We have our default error policy set to 'abort-job'.  Sometimes there are print jobs that for whatever reason do not print, stay stuck in queue as 'processing', and prevent subsequent print jobs (in that queue) from printing.  Right now, our solution to this is to stop the printer, cancel the job, and restart the printer.  We would like it if CUPS could automatically cancel these problem jobs and let subsequent jobs through.  Any suggestions?  Thank you.
