Canon LBP2900 printer only works when connected after log in

  • 772

I have a Canon LBP2900 printer and Ubuntu Natty 64-bit.

After quite some trouble I found here a nice guide explaining a installation procedure with packages from this ppa.

I followed the guide and did all steps and now the printer works if it is connected (or powered on) after login.

If I connect it already before my computer is started, the following happens. A second printer (LBP2900-2) is automatically created and the command sudo /etc/init.d/ccpd status only gives one pid, while it should give two.

How can I fix this?

An extra detail that can help; normally the device uri is ccp:/var/ccpd/fifo0. Actually this path (/var/ccpd/fifo0) does not exist, but that does not seem to matter. The printer that Ubuntu automatically adds when starting up with the printer connected has usb://Canon/LBP2900 as uri

The output of grep lp /etc/udev/rules.d/*:

~$ grep lp /etc/udev/rules.d/*
/etc/udev/rules.d/85-canon-capt.rules:KERNEL=="lp*", SUBSYSTEMS=="usb", ACTION=="add", SYSFS{idVendor}=="04a9", RUN+="/bin/bash /etc/init.d/ccpd start"
/etc/udev/rules.d/85-canon-capt.rules:KERNEL=="lp*", SUBSYSTEMS=="usb", ACTION=="remove", RUN+="/bin/bash /etc/init.d/ccpd stop"
printing

  1. It sounds like udev is somehow confused. I suggest double-checking your steps on that page under the heading Starting/Stopping on USB Add/Remove. Assuming that is all correct, add the output of the following command to your question:

    grep lp /etc/udev/rules.d/*
