One thing you need to check is the access rights to the printer device.
The device that you want to print to (e.g. /dev/lpt0) needs to belong to
the "cups" group (which should exist, along with an unprivileged user
named "cups"), and that group needs to have read/write access.
If you are using a parallel port printer, add the following to
devfs.conf(5) and reboot, or use chown/chmod to correctly set the values:
# Give cups printer access
own lpt0 root:cups
perm lpt0 0660
If you are using for instance a USB printer, you need to add the
following to your ruleset in devfs.rules(5)and reboot, or use
chown/chmod to correctly set the values:
add path 'ulpt*' mode 0660 group cups
