Subscriber Print Network

Hi all,
Not sure if this is a php question vs. a network question.
Planning on opening a wifi coffee shop and and wanted to add some services. So I built a site that offers up a signup page and allows customer to get discounts on coffee and stuff, not really that tough. Where I am a little perplect though is I want to offer a print network / printer access in the coffee shop for local college students, but only if they are a subscriber to our coffee shop website and want to control it so they have to been in the coffee shop to print.


Any idea's where I might start with something like that?
Using
Apache / PHP and MySql on a Linux system....

Thanks for any suggestions

I would set up the printer as an http:// network printer using CUPS....after you do that, restrict it to those only providing a valid account and redirecting it to the printer. It's a little tricky, but it works.
