I don't have a solution for your problem, but a warning for people who
rename their printer devices with udev.

Starting with the latest stable CUPS, when using "usb:/dev/*" device
URIs, the device node must be below "/dev/usb", and must be the real
device, not a symlink.

In my case, I had renamed my printer device to "/dev/printers/hplj", and
CUPS refused to use it. Even a "/dev/usb/lp0" symlink to it didn't help.
So I am now stuck with an ugly "usb://HP/LaserJet%201320%20series"
device URI, as auto-detected by CUPS.

Answer:

  ls: /dev/usb/lp0: No such file or directory

Hmm! Well done, Neil. Checked in the /dev/ directory and sure enough,
there is no /dev/usb but there is /dev/bus/usb/

Tried ls /dev/bus/usb/lp0 and /dev/bus/usb/004/lp0 all with the same
result. Not sure where to go from here, but it looks either as though
CUPS is assuming an invalid directory structure, or doesn't know how to
work with udev.

Any further thoughts?

Run "tail -f /var/log/messages" and connect the printer. the output
should tell you where the printer appears, then you can change the CUPS
config accordingly.
