Hello
I just upgraded my Ubuntu 11.04 to 11.10. Unfortunately, In Ubuntu 11.10 my canon LBP2900B LaserShot Printer stopped working. I have googled a lot and tried many guides which were for elder version of ubuntu, but It is still not working.

Can anyone guide me what to do??? I can provide u any useful output if required.

Hello !

I also had this problem, already decided as follows:

1. if device /dev/usb/lp0 not found in folder - this means no driver usblp which is used for printers CANON
This situation appeared after upgrading from 11.04 to 11.10 version UBUNTU

put: lsmod | grep usblp
If it outputs nothing, load the module : sudo modprobe usblp
and try again toy view loaded modele usblp

2. Not loading this module, the problem: /etc/modprobe.d/blacklist-cups-usblp.conf
view:

# cups talks to the raw USB devices, so we need to blacklist usblp to avoid
# grabbing them
blacklist usblp

itself system blocked his boot module !!!

change: #blacklist usblp
and save and reboot and control present /dev/usb/lp0

3. restart CUPS: sudo /etc/init.d/cups restart

Device /dev/usb/lp0 - it is use for printers
* Restarting Common Unix Printing System: cupsd [ OK ]
* Restarting Canon Printer Daemon for CUPS: ccpd [ OK ]

CUPS_ConfigPath = /etc/cups/
LOG Path = None
UI Port = 59787

Entry Num : Spooler : Backend : FIFO path : Device Path : Status
----------------------------------------------------------------------------
[0] : LBP2900 : ccp : /var/ccpd/fifo0 : /dev/usb/lp0 : Modified



4. test you printers to print. if not work may be to restart printer off-on and try again to print (need for me)
Unfortunately I still unsolved as finally ibavitsya from having to restart the printer. I do not know very well linux

5. I hope uvas already installed printer driver, if not then use the assembly h**p://nixtech.ru/datatrans/lbp2900-pkg.tar.gz , unzip the folder and run the script
type: sudo sh install-lbp2900.sh and follow .... (ask Y Y) (i am use this pack)

6. after this step im booting ubuntu and printer off-on = printer Ready to Print !!!


7. I hope this helps anyone else



PS: and another metod may be work h**p://translate.google.com.ua/translate?sl=ru&tl=en&js=n&prev=_t&hl=ru&ie=UTF-8&layout=2&eotf=1&u=http%3A%2F%2Fgnu.su%2Fnews.php%3Fextend.726

Great, I was trying to get started my printer for last 3 or 4 days. But result was 'zero'

Now, I can use the printer

Thanks a lot


Now, a second question. Can I use the printer without on-offing the printer or restarting the cups every time???

At this point restart the printer is no longer needed. After loading UBUNTU printer ready to print. (although I had to reinstall it). Recently updated CUPS several times.
