Installing canon LBP5000 laserjet printer

Question

I just recently upgraded from PHP 5.2.1 to 5.3.5. Had problems with my joomla sites, so I downgraded to 5.2.6, but now all my sites are running super slow. What could be the cause of this in the php ini file?

Solution 1

I am using:

• Ubuntu version 11.04
• A Canon LBP500 connected via the network

When I followed Guide: https://help.ubuntu.com/community/CanonCaptDrv190 I got my printer working, but captstatusui (showing printer status in a GUI) gave a bufferoverflow.

When using script: http://radu.cotescu.com/how-to-install-canon-lbp-printers-in-ubuntu printing and captstatusui worked perfectly, but after a while my Update Manager complained I had a partial finished install and removed the drivers again. Maybe something to do with not specifying a correct package repository?

Anyhow, I made a copy of the working captstatusui binary, let the update manager remove the drivers installed via the script of Radu Cotestcu. Now I have the drivers installed according the first Guide, and use them in combination with the copied version of captstatusui.

Maybe not that elegant, but it works for me

Solution 2

If Status monitor reports error "Check the DevicePath of /etc/ccpd.conf", then you probably don't have usblp kernel module. Run the following command:

lsmod | grep usblp

If it outputs nothing, load the module and restart ccpd:

sudo modprobe usblp
ls -l /dev/usb/lp0
sudo /etc/init.d/ccpd restart

Note: As of Ubuntu 11.10 (Oneiric Ocelot), usblp has been deprecated and will not be automatically loaded when you connect your USB printer (see bug #842823]).

If the status monitor works but printing does not, make sure that /var/ccpd/fifo0 actually exists:

ls -l /var/ccpd

When missing, it can be added manually:

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

Well it could be one of the settings, which we are however unable to debug since you didn't show your php.ini or phpinfo comparisons between your php5.3 and 5.2 setup.

Thnx for your reply, but I have some questions left. Did you install the printer for the first time? Is the printer directly attached to the netwerk or by another computer? and most important: how do I clean up the mess of my previous installation attemps.
