I'm a unix admin at a lab, and we use Pykota to manage print quotas (essentially, each user has a 'balance', each printer has a 'cost per page', and Pykota manages that). I've grown to hate Pykota (it was installed before my time), and so have the other admins. Unable to find alternatives, I thought I might be able to write my own. Requirements: - Per-user granular modifications - ability to precisely set a user's quota, or give him unlimited quota. - One printer will be enough. - Printable from Windows workstations over Samba (this is what makes it tricky, otherwise I'd just hack up an alternative lpr) - Users need to be able to see how much quota they have left Bonus points: - Web-based interface for administration (simple if data is kept in SQL, then I can use Rails) - Web-based queue-view (much less important) - Error message when out of queue displayed on the Windows box while attempting the print. It would be nice if I could just have an "upload your file, we'll print it" solution, but since people want to print Powerpoint slides (in Hebrew, which Openoffice doesn't properly convert), that's not possible. (Adobe Acrobat isn't installed on the workstations, so we can't make people upload PDFs. The big questions are these: - Do I 'spoof' a printer for the queue? Or do I 'block' other printers like Pykota does? Something else perhaps? - How do I count pages? Will postscript be able to do that? Any input would be appreciated.

Install ghostscript, and use that to produce .ps in some directory when people "print", which you can then convert to pdf if you want (ps2pdf) or send off as is to the real printer. They still get to click on file > print, and you still get the benefits of upload your file and we'll print it scenario. As far as displaying a message on the windows box, I believe you can use samba to send 'net send msg' style messages.
