Can you do the following test:

Run

lsusb

and look for the line of your printer. The printer has a Bus and a Device number. Now run

sudo chgrp lp /dev/bus/usb/<bus number>/<device number>
sudo chmod 664 /dev/bus/usb/<bus number>/<device number>

with <bus number> and <device number> being padded with zeros to be always of 3 digits (8 -> 008, 11 -> 011, ...).

Example:

till@till-laptop:~/ubuntu/cups/bzr/debian-trunk$ lsusb
Bus 002 Device 029: ID 03f0:1c02 Hewlett-Packard PhotoSmart A710 series
till@till-laptop:~/ubuntu/cups/bzr/debian-trunk$ sudo chgrp lp /dev/bus/usb/002/029
till@till-laptop:~/ubuntu/cups/bzr/debian-trunk$ sudo chmod 664 /dev/bus/usb/002/029

Then try to add a print queue and print to it. Does it work?

Note: Do not turn off or unplug the printer during this procedure, otherwise you will have to do all steps again (device number changes then).
