Which version of CUPS are you using? I have 1.2.3 (on Edgy) and if I specify "socket://printer:9101" (no trailing slash) the data gets correctly sent to port 9101.
-- Dapper (updated today) -- cupsys will not use a jetdirect port other than 9100 https://launchpad.net/bugs/28405 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
