I have just installed "task-printing-canon" on my KDE-mini and by doing
[root@localhost gert]# lpinfo -m >>/home/gert/Desktop/120108-KDE-mini_available_printers.glk
I have sent all printers available to CUPS server to a file on my desktop. Opened the file in kwrite, F7 and type "sort" the file is then nicely ordered.
Using the normal search for mp280 or pixma. I had some trouble with capitals letters in the search, forgot to turn on/off something but in the end I found:
gutenprint.5.2://bjc-MULTIPASS-MP280/expert Canon PIXMA MP280 - CUPS+Gutenprint v5.2.7
gutenprint.5.2://bjc-MULTIPASS-MP280/simple Canon PIXMA MP280 - CUPS+Gutenprint v5.2.7 Simplified
(I don't know why but I find it a bit that our Canon S820. used in Windows does not show, not a problem as I don't use this on Linux yet)
