Bug#377079: cupsys: hp_laser (Default Printer) "Printer not connected; will retry in 30 seconds.

["Adrian Dziubek" <adrian.dziubek@gmail.com>]

I have the same problem with HP DeskJet 610C. I use the workaround:
chmod o+rw /dev/lp0
but it get's reset by the udev on every reboot.

I stubled upon that from this forum:
http://www.debianforum.de/forum/viewtopic.php?t=69879&sid=05d3ab004de1be09ab2fef74dce70f5a

I basically have the same symptoms as described there:
"Unable to open parallel port device file "/dev/lp0": Permission denied"

I already loaded the lp module by manually putting it into
/etc/modules, this behavior probably also deserves a bug. Before doing
so, I got the message:
"Printer not connected; will retry in 30 seconds..."

...and I had to remove the /var/run/cups/cups.sock:631 and leave only
localhost:631 with "kcmshell printers" for it to cooperate and display
printers in the dialog at all.
