Printer pause

Hi list, On a SUSE 9.2 File/print server, I have problem that for some reason, the printers are paused every now and then. For no apparent reason. Both are USB printers, one a Designjet 500 (set up as a raw queue, windows drivers installed on the clients), and a OfficeJet D145 (Yast picks this one up correctly). Both print perfectly fine for a couple of days, then all of a sudden the printer queue box on windows says printer is paused, and in the cups interface it is paused/stopped, and I have to start it again. Any ideas why? Also, is there a command that would start/restart the respective queues? Thanks -- Hans du Plooy SagacIT (Pty) Ltd hansdp at sagacit dot com
