I'm looking for a printer to use on a network of about 4 computers (both Mac and PC) and it will be used entirely for documents (colour isn't a priority). Additionally, it will be used quite heavily, so I would prefer a very long cartridge life. I'm guessing the average printing will be about 30-50 pages per day. The printer will be used for generic home use in addition to a home office. Provided the printer isn't the size of a photocopier, I'm not too worried about size/bulk. So, do you have any recommendations? What approximate price will I be looking at? I'm sorry, but I don't know where to begin with this stuff. Finally, I would like this to be a wireless printer, but I don't know if my current router can allow that (D-link WBR-2310). I would appreciate any/all help! Thank you.
