Hey.
I've been trying to get the printer working on my parent's PC, which is
now actually using their Debian install now that their XP install has
died and I'm in no hurry to reinstall it. ;)
Interesting issue though, namely, the printer device and cups.
Basically, I have cups using the default users and groups, namely "lp"
and "lpadmin". The groups are all populated (over -populated for my
testing, actually, but I digress), but it just doesn't work. The
permissions on the device "/dev/usb/lp0" are the default "crw-rw----
root:lp", but even though I've dumped everyone I can think of into the
"lp" group, it doesn't work unless I either give ownership to the "lp"
user, or give everyone rw rights. The group side of things just doesn't
seem to work at all. I've looked at the processes when printing, and
AFAIK they seem correct ( daemon as "root", children as "lp").
I've just modified the udev rule to set the user as "lp" to let them
print, but I'd like to figure out why it's not working as expected. Any
ideas?
Is the printer known to work in Debian? What are you using to configure
the printer, the gnome-printer menu item or 127.0.0.1:631. Try to avoid
using the gnome-printer-config because it is very buggy. Open up
127.0.0.1:631 and go to admin and add printer and it will walk you
through a little wizard. When all is done it will ask for your username
and password that you use for logging onto the computer, don't use root.
If this don't work then add the user that your parents will be to
lpadmin. How I did it was to go to gnome-user-groups menu item and
select group tab>lpadmin>properties button>select my name and click add.
Now that you added the user try 127.0.0.1:631 again and it should
accept your username and password. assuming the printer works in the
first place under Linux.
