Cons: Will not manual feed without pressing the ok button several times at the printer. HP website horribly slow. Tried several drivers with no luck. Other owners complain of same issues and no fix that I could find.
Summary: We replaced two HP 4350TN's with the M601DN's and we are extremely pleased with their performance. They are fast and the best part is the duplexing ability! We print Material Safety Data Sheets for each of our orders and the ability to print these documents in duplex mode will save us a ton of paper! Reasonably prices enterprise level printer... great upgrade choice!
