Why does an uninstalled Canon LBP 5050 printer keep reappearing? I used to have a Canon LBP 5050. It is no longer connected to the network or the Mac. I removed the printer from: "System Preferences → Printers" and even removed the ppd from /Library/Printers, using Terminal, but for some reason it constantly reinstalls itself every time I reboot my machine.

As far as I can tell there is no special Canon software installed or gets "called up" as a logon item.

Does anyone have any ideas?
Somewhat of a hidden feature, you might want to try resetting the printing system.


Go to the Print and Scan preference pane.
Right click in the list of available printers (mine's empty).
Select "Reset printing system...".
