I have this in my /etc/devfs.rules file on a system successfully using
CUPS with a parallel port printer:


[localrules=10]
add path 'lpt*' mode 0660 group cups


(I also have 'devfs_system_ruleset="localrules"' in my /etc/rc.conf
file.)

That makes sure that CUPS can access the lpt* devices (including the
lpt*.ctl devices).  Mode 0660 also ensures that not everyone can access
lpt*, just root and members of the cups group (i.e., CUPS).

Cheers,

Paul.
