Description of problem: This is probably a dup of https://bugzilla.redhat.com/show_bug.cgi?id=455003 On one of my Fedora 9 x86_64 systems, I started getting the error message in the Summary ... on another system with the same updates, things work just fine. This did not start until the last week or so (before that it worked fine and as best I can remember, I did not change the printer configuration). On both working and not-working systems, the printers were configured with the system-config-printer gui. There are two postscript printers: an HP4000 Laserjet as lp0 (LPD interface) and an HP 2550 ColorLaserjet as lp1. Default printer is lp0. I have tried deleting and then reinstalling the printers, changing the default from lp0 to lp1, but nothing works. Although the problem occurred with a locally written program (which has a fork(), execvp(lpr), and passes data via a pipe), I have gotten it to reproduce with just "lpr". Specifying a printer works fine and the output prints. Using firefox to print works with no problem. For whatever it is worth, I get the same error with "lp" and "lpr". Version-Release number of selected component (if applicable): Fedora 9 with (more or less) current updates How reproducible: yes ... on the system where it is broken. On another Fedora 9 x86_64 system with the same updates, it works fine.
Oops. I am closing this because the problem MUST BE something on my end!! I have now verified that the problem only occurs with one userid (???)
Sounds like all the other users have a 'personal default' printer, i.e. set with the equivalent of 'lpoptions', but there is no system default printer (which you can set with system-config-printer).
