Printing form both Linux and Windows XP

I have both Windows XP and Linux-Unix installed in our
Computer lab. Our default OS is Windows. So all the
printers are taken care of in this environment only. But
if someone sends prints from Unix commands or Linux then
the files won't show on the printer queues and it will be
printed even if I keep printer paused and under watch.

Is there any solution like I can see Linux prints in
queues, or maybe I can access printer queues from Linux
so that I can prevent unauthorized printing??

Thanks and regards,
