Since you are able to print I see nothing special in the error_log. Did you do dist-upgrade from breezy or fresh install of dapper? It would have been nice to have an error_log, /etc/cups/cupsd.conf and /etc/cups/cups.d/* before you did downgrade to 1.2.0. You should point other users with the same problem to this bug report to find out more.
