Thanks for your helpful bug report. Was this after a fresh installation of Gutsy or after updates? As a general rule, Linux uses /etc/hosts to enumerate specific machines on the local network including printers. I don't know if CUPS adds this entry automatically. I usually add it manually, knowing that many things in Linux break without having accurate /etc/hosts entries.
