Printing

Installing printers in Ubuntu may be more challenging than other stuff, but in the end you will see that it is not so difficult as it seems.

I think that I was unable to install my Canon printer LBP-1120 due to small errors that I did not notice for a long time.

INSTALLING Canon printer LBP-1120 in 12.04 and 12.10 (and the other Ubuntu-based Linuxes, like Linux Mint 13 and 14)

• Download and install the drivers from here. These are version 2.4. in case of update look up this Ubuntu page.

• Enter the Terminal in root (sudo su).
• "Restarting cups". For deb install  this should be
  /etc/init.d/cupsys restart
  But in 12.10 it is
  

  /etc/init.d/cups restart

(service cups restart should give the same result). This should give something like:

cups stop/waiting
cups start/running, process 2758

• "Register the printer (PPD) with the print spooler."

sudo /usr/sbin/lpadmin -p LBP1120 -m CNCUPSLBP1120CAPTK.ppd -v ccp://localhost:59787 -E

• sudo gedit /etc/modprobe.d/blacklist-cups-usblp.conf

And in there paste these lines:

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

• "Register the printer in the ccpd daemon setup file."
  
  /usr/sbin/ccpdadmin -p LBP1120 -o /dev/usb/lp0

 This should lead to something like a table. 

• "Start ccpd daemon"
  # /etc/init.d/ccpd start 

sudo /etc/init.d/ccpd status 

to see if you see 2 numbers.

If not, procedure has to be restarted.

If yes, better restart computer. In order to print, start ccpd (sudo /etc/init.d/ccpd start) and connect printer after that.

Consider these if printing doesn't work:

• connect/start printer after login
• /etc/init.d/ccpd status to see the 2 numbers
• sudo /etc/init.d/ccpd start to Start ccpd daemon

If all is ok, the ccpd daemon has to be restarted anyway after restart, so, to make it start automatically with the system:

sudo update-rc.d ccpd defaults

INSTALLING HP LASERJET 1018 PRINTER IN 12.04

In 12.04, the driver is already installed (hplip) but the printer does not work initially.

Connecting the printer asks for proprietary plugins and opens a terminal procedure that does not seem to work. 

So, open the terminal and

sudo hp-setup

This opens a HP GUI installer that does all the job, including adding the printer.
