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?

  • How was the printer connected? USB directly? Via an Airport device? Using a network printer server?

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...".
