Hi,
I'm planning on setting up a terminal server for about 50 remote users. All these users are on different locations. They will be connected with a thinclient to a linux terminal server (running debian). I've done some tests with NX and it seems very promising. All users have a laserprinter connected to their thinclient (using LPD printing). So I need to define all the printers in CUPS on the server, no problem there. But my concern is this: I don't want a user to 'see' all the printers of every location in his openoffice print dialog - or any other application. I just want them to be able to see the printer at their location.
Is this possible? How do I handle this?

Your on the right track. The cups daemon is very versatile, you can set up classes, ACLs etc... Which I would think should work. I don't know your environment, but you say "different locations." Can you define that a bit more?

If I remember correctly you can also permit users on a group or by user basis as well.
