Perhaps the proper approach is "severe administrative

you print in colour anyway, you'll get sanctioned, then fired".

Problem is that the queue is set B&W in the CUPS config (just tested this
from the SuSE box acting as the print server, however I think that the raw
option for the -o raw is the culprit here on the print command option line
for lpr-cups. Do Samba shared printers require this option?

Unfortunately, my boss is not giving me the option of this being resolved
through a non-tech solution. Either I find a way to block this, or I have to
move printing back to a Windows Server 2003 box and then screw over all the
Mac and Linux workstation users here that cannot use the enforced Windows
print driver security settings.
