After updating CUPS to 1.2.6 (and 1.2.7 behaves the same way) my HP LAserjet 1200, which is connected through USB port to the server, has stopped working. After whole day of re-emergeing dependencies and fiddling woth everything, I have found the reason: its usb backend - "/usr/libexec/cups/backends/usb" expects to see usb printers in /dev/usb conventionally named (lp0,lp1 etc). SInce I had written extra rule for hotplug that makes my printer device node named "/dev/usb/ljr_1200", backend did not recognise it and preinter under CUPS refused to work. Simple link "ln /dev/usb/ljr_1200 /dev/usb/lp0" has remedied the situation.

Please a) complain upstream to the cups devs so that they can change their usb backend or b) do not use an udev rule to rename the dev node.
