[plug] cancelling a CUPS print job

[Adrian Blockley]

I recently had similar problems with CUPS not flushing the print buffer. It was a big job and several power cycles did not flush the buffer. The only way I could get the printer to stop was to unload the kernel printer modules after stopping the cups daemon.

I think the relevant modules are: 

parport_pc             28008   1 (autoclean)
lp                      6912   0 (autoclean)
parport                26752   1 (autoclean) [parport_pc lp]

Once I unloaded the modules I restarted CUPS and restarted the printer and all was well. 

Cheers

Adrian
