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.
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
