Hi,

printer.conf looks all right.

Cups installs four files with names that are the same as print utilities
which are part of the FreeBSD base.

cups gives you:

/usr/local/bin/lp
/usr/local/bin/lpq
/usr/local/bin/lpr
/usr/local/bin/lprm

FreeBSD already has:

/usr/bin/lp
/usr/bin/lpq
/usr/bin/lpr
/usr/bin/lprm

If you rename the four files in /usr/bin your test page may print.

$ sudo sh
# id -u
0
# cd /usr/bin
# for a in lp*; do mv $a  bsd-${a}; done
# exit


The man pages in /usr/share/man/man1/ could also be renamed.
Cups has its man pages for those files in /usr/local/man/man1/.

If the BSD files are not renamed the files installed by cups-base are not executed
because of the order that directories are listed in the environment
variable PATH.

When you upgrade, the adjustments may have to be made all over again.  However, binary
upgrades do not seem to revert these changes (at least not in my experience.)
;-)

See the output of "ls /usr/local/bin/lp*"  and  "ls /usr/local/sbin/lp*" for more files
that the cups-base port has installed for you.

HTH,

Cary
