I used an amalgam of
http://www.unixmen.net/index.php?option ... s&Itemid=2
and an earlier Ubuntu post
https://help.ubuntu.com/community/Hardw ... n_LBP_2900
the only useful extra from the Ubuntu was how to locate the ppd file
I essentially copied and pasted the commands from the unixmen post; (adding appropriate descriptors for printer and ppd file);$ ls /usr/share/cups/model/ | grep CNCUPS
these printers seem to cause some folks some problems; but now Canon offer .deb as well as their initial .rpm packages, all seems to go well
