Hello :)
Take courage, my friend :) You are not alone :) I don't know what
caused it, and I don't know what ended up permanently fixing it, but I
did discover a workaround that worked every time. In my case, when I
switched runlevels (I Suppose that rebooting would have done it, I never
tried it :)) when I came back to runlevel 5, our printer was "gone" My
workaround, even though the startup messages said that CUPS had started
ok, was to run:
/etc/init.d/cups restart
After doing this, in KControl, a few times I just sat there and watched
our printer magically reappear :) Then all was well.
(I use Fedora Core 2. If you don't, the command I gave might need to be
slightly altered for your system.)
If this helped you, I will take great pleasure in that :)
