Hi, Since friday last week I have a HP4050 laserprinter connected on my Suse 9.3 server. This worked fine until this afternoon. Now in Cups (http://localhost:631) I get the following message : Parallel port busy; will retry in 30 seconds. Device URI: parallel:/dev/lp0 What I tried : Stop the printer in Cups, and power down and up the printer. Then I restarted the printer. Not good. Then I killed the 'parallel' child of Cups (maybe this was wrong), and tried to print again, no good. Then I remembered I could 'kill' Cups by rccups stop. Tried this and restarted Cups, not good. So what can I do more ? I tried to rmmod the parallel modules (lp, parport_pc, parport) but that doesn't work. I hope I don't have to reboot the server because it's busy right now. Thanks for any help you can provide. -- Met vriendelijke groeten, Koenraad Lelong R&D Manager ACE electronics n.v. -- Check the headers for your unsubscription address For additional commands send e-mail to suse-linux-e-help@suse.com Also check the archives at http://lists.suse.com Please read the FAQs: suse-linux-e-faq@suse.com

http://en.opensuse.org/SDB:Installing_a_Printer especially the part about BIOS settings for parallel port printers. Mode must not be ECP/EPP and DMA should be off. This is SDB article is for older versions of SUSE but the information is still valid on newer hardware and SUSE. Stan

My guess is that the printer is reporting "busy" to the computer. There is a line in the cable for that. You could try with another cable, or conecting the printer to another computer to find out.

So far, not wrong. I do that to stop print jobs all the time.
Then I remembered I could 'kill' Cups by rccups stop. Tried this and restarted Cups, not good. So what can I do more ? I tried to rmmod the parallel modules (lp, parport_pc, parport) but that doesn't work.
Shouldn't. Did you reload them?

Try "http://localhost:631/printers". There is a button for stopping/starting a printer. - -- Cheers, Carlos E.

Sorry for responding so "late". I didn't see any responses, so I rebooted the machine. All is fine (for now ?). The printer was working OK but suddenly it stopped.

I seem to have explained bad : I tried to unload the modules and this didn't work, so they were still loaded.

Tried this reveral times. I'm going to read Stan's link and check that out. Another boot for the machine I fear. Anyway, thanks for the help. -- Met vriendelijke groeten, Koenraad Lelong R&D Manager ACE electronics n.v. -- Check the headers for your unsubscription address For additional commands send e-mail to suse-linux-e-help@suse.com Also check the archives at http://lists.suse.com Please read the FAQs: suse-linux-e-faq@suse.com
