My wife and I have our computers networked (with cable modem/router, etc.) Anyway, we have an HP deskjet (940c, I think). If possible, I'd like to hook it to a print server so we can both easily access it (right now I use the parallel plug for her PC and the USB for my mac, but we have to turn it off each time we switch who's printing). HP offers a print server that runs $175 or something. I've seen other 3d party servers that are much cheaper. Will these work just as well (or at least adequately), or do HP printers work only with HP servers? Thanks!
