Here’s what I have done so far:

  1. CTRL-Clicked in the “Click to Add Printer” Pane of Print & Fax in System Preferences and RESET the printing system.
  2. Deleted the /Library/Printers/Canon/BJPrinter directory.
  3. Deleted the /CFMSupport/BJExtDDI.cfm file.
  4. Restarted my computer.
  5. Downloaded the latest Canon install package, mp600osxpd583ej7.dmg, with a creation date of 2007-11-08.
  6. Installed the Canon MP600 583.pkg package.
  7. Restarted my computer.
  8. Reconnected the MP600 to the Airport Extreme.
  9. Returned to Print & Fax, clicked on Add Printer. The MP 600 turns up in the dialogue window that comes up and is listed as a Bonjour Device.
  10. I clicked ADD.
  11. The process hangs until I get an error sheet:

An error occurred while trying to add the selected printer. Error:-9672

Every 8 seconds one of these is getting posted to the console:
