CUPS supports (since 1.4 I think) the auth-info-required printer attribute
("username,password" for your usage) and the auth-info operation attribute (two
strings containing the required auth info). The auth-info can be specified both
at job creation and later using the CUPS-Authenticate-Job operation. Jobs that
require authentication are held with the auth-info-required reason. And IIRC
Tim Waugh's printer monitor for GNOME already supports doing the authentication
when it sees this.
Right now there is no CUPS command to re-authenticate a job from the
command-line, but I could look at adding it to the lp command's "-i" option...
