I guess I wasn't clear in my previous post, the changes I made to udev.permissions did *not* change the owner from root to lp on the next boot. I did change the printers in the rules file (as suggested for the usb entry in previous post in this thread) and that seems to have worked. Can some of the more experienced Debian users on this list explain what is going on here? It seems obvious to me that cupsd should be run with rights that allow it to access printers, shouldn`t it?

Just replace usb in the rule with whatever bus your printer appears on, and hopefully that will fix your permission issue. See /usr/share/doc/udev/writing_udev_rules/index.html (this should be on your system), also man udevinfo. John -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

I find I also have to use an old /etc/cups/cupsd.conf file if I want to print as a user (from KDE at least) - I'm in the process of trying to work out why. Judging by the limited response to my post this doesn't seem to be a widespread problem. Although I'm a real Debian fan, it took me a while to get to the bottom of this problem and I must say I'm really frustrated. This seems like a basic issue: cupsd should run with rights that allow it to access printers - or am I missing something here? Thanks for your post, I'll try what you suggested!
