This is really frustrating. I am trying to install LBP6000 in Ubuntu 12.04 without any success.

(Well, I had success about a week back when I first bought the printer and finally printed pages after a struggle of several hours. Then today it suddenly stopped working and I uninstalled everything and started from scratch. Now, I seem to have lost the way.)

My steps

1. Downloaded the latest Canon driver from Canon site. File Linux_CAPT_PrinterDriver_V240_uk_EN.tar.gz
2. Got the radu script (I am allowed only two hyperlinks, so can not put the link here. You can Google radu Canon)

3. Changed the /etc/modprobe.d/blacklist-cups-usblp.conf file as instructed in, Official Documentation. (See the section Ubuntu 12.04 Install). Now this file looks like,

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

4. Rebooted my machine

5. Changed the port in radu script to 59787 as instructed in the link at step 3. (Again see the section Ubuntu 12.04 Install, or see the comment at How to Install Canon LBP Printers in Ubuntu. Also put the latest deb files from step 1 in the appropriate directory of this script.

6. Ran the radu script. A printer, LBP6000 got added. Not two printers, one to be disabled, as appeared in the message on the terminal after running the script.

7. sudo /etc/init.d/ccpd status shows,

   Canon Printer Daemon for CUPS: ccpd: 3142 3139
   

   Results

8. The printer does not print. Printer state (from System Setting->Printing, or at cups http interface localhost:631/printers/LBP6000) goes from Idle to Processing, a job appears in print queue, and then the job disappears and the printer state goes back to Idle. The actual printer does not even blink.

Diagnostics (got help from the link in step 3, Troubleshooting)

1. captstatusui -P LBP6000 shows communication error

2. lsmod | grep usblp did not show anything. After running, sudo modprobe usblp, shows

   usblp                  17885  0
   

   However, ls -l /dev/usb/lp0 gives,

   ls: cannot access /dev/usb/lp0: No such file or directory

3. /var/ccpd did not exist, created,

   sudo mkdir /var/ccpd
   sudo mkfifo /var/ccpd/fifo0
   sudo chown -R lp:lp /var/ccpd
   

Any suggestion will be appreciated. Do not know what to do.
