A:Answer Good evening ShiShi. We appreciate you taking the time to ask questions. The letters at the end of our LaserJet model numbers signify the defining features of the product. F = Fax, W = Wireless, D = Duplexing (Double-sided printing), N = Networking, etc. If you intend to purchase a model that is wirelessly capable, then you will want to look for the HP LaserJet Pro m479fdw. Otherwise, yes. The HP LaserJet Pro m479fdn is network-ready and will work with an ethernet cable as intended.
