Summary: I bought this M401dw printer to replace a sixteen-year-old HP6 laser printer that had served faithfully since new without any problems during its lifetime except for its limited amount of memory. I bought the wireless version of the M401 just for future flexibility but actually installed it as a wired Ethernet printer on my small LAN. The software installations from the CD, on Windows 7 and Vista, went efforlessly.
Summary: I have always been a HP fan. I went from an 1120 laser printer to HP LaserJet Pro 400 Printer M401dw. The quality is not in the new printer. It has paper hang ups and you have to stop pull the cartridge out pull the paper out from the back. Not worth the price.
