it's working again, why?
Well, my printer has started working again. The problem is I have no idea why. As far as I can tell I didn't do anything differently, I shut my system down last night, as I do every night, then this am I rebooted and fired up OOo, tried it again, and to my surprise it worked. I printed several things that had been backing up, no problem.
I don't believe in magic, but I can't think of any rational reason for this to happen. My best guess is an intermittent bug in cups, but even that doesn't make a lot of sense since I did print a test page.
If anyone has any idea I would love to hear from you.
