This printer is quite possibly the most reliable I've ever had the pleasure of using. Coming from the 90s, as standard it has only a parallel and serial port for connection, but it's simple to add a JetDirect card for network printing. These are widely available and pretty cheap these days. Drivers are available for almost any system you can imagine so you'll have little problem getting it to work.
Aside from the network card, one other thing you might want to do is obtain some additional memory. This is also reasonably inexpensive and allows complex documents to be printed much quicker than with the standard 4MB.
Print quality is superbly crisp and pages come flying out (not literally, thankfully - imagine the chaos) after the initial warm-up of a few seconds. The main built-in auto-feeding paper tray is large enough on its own, holding a whole ream of A4, but an additional one is available which sits beneath the printer and holds an extra 500 sheets.
Toner cartridges aren't especially cheap but you'll need to do a lot of printing to get through one and less expensive remanufactured/compatible versions are available.
