Install and Use Canon MP620 with Linux

[admin]

I was able to get the printer working on my 64bit machines running 13.10 by installing cups-backend-bjnp

sudo apt-get install cups-backend-bjnp
Then open printers, click on add printer. Select Enter URI, then enter the device URI (i.e. "bjnp://192.168.1.112")
Click next Select Canon from the listbox.
Click forward Select PIXMA MP620 from the models listbox
Click forward Add any descriptions you like then hit Apply and try to print a test page.

I recommend setting your router to provide the printer a static ip address so that you won't have to re-add the printer every time your router resets.
