Cups runs into a printer detection loop

[ptashek]

OS: Ubuntu 7.04
CUPS: 1.2.8-0ubuntu8
gnome-cups-manager: 0.31-3ubuntu5
kernel: 2.6.21.1 + CK2 low latency patches (uses the same config as 2.6.20-15.27)

Printer: Samsung ML-1710, USB, monochrome laser

As soon as I start a GNOME session and turn the printer on it is detected by the system and gnome-cups-add starts allowing for configuration of the detected printer. That is fine and working. However, every time I turn the printer off and turn it back on the same process happens again and I have only two options: cancel, after which the already installed printer refuses to print or go ahead with the wizard which results in the system now having two instances of the same printer AND gnome-cups-add entering some odd loop. It simply keeps re-detecting the printer every couple seconds and after a while I have like... 20 windows blinking on the taskbar each asking me to add a printer I already have properly configured once!

What I have done so far was kill-off gdm, stop cupsys, remove /etc/cups/printers.conf and /etc/cups/ppd/* and /var/run/cups/*, then restarting cupsys, gdm and powering on the printer - same story.

The problem is that the printer setup tools currently in Ubuntu are not prepared for printer auto-installation, as they cannot check whether there is already a print queue for the newly connected printer.

printerdrake (https://blueprints.launchpad.net/ubuntu/+spec/printerdrake) has such a feature and so it is highly recommended to switch to printerdrake in Gutsy.

We have changed the default print management system in Ubuntu from gnome-cups-manager to system-config-printer because g-c-m is no longer maintained. Please open a new bug against system-config-printer if you still have this problem with Gutsy or Hardy. Thanks!
