Prints from one computer on the network but no

Look under the "network setup"(or closest thing you can find) menu on the printer, and check number of clients,, sometimes it can be set to 1, in which case the the first computer that talks to it, will be the only computer that can.

With live responses I could help further but this is the first thing that comes to mind, it happened to me in the Coke building in NYC, and that fixed it right up.

I hope this helps!!
