Summary: Discontinued model, but good quality HP Laser printer. Works with duplexer (sold separately) for saving paper costs. Use in law office very durable. The 4015 uses larger size, better priced toner than the 4014 as well as the smaller toner for 4014.
Summary: I needed a printer that had a good envelope feeder. I normally buy a different brand, but thought i would give HP a try. I figured they would have a solid platform for business use and envelope processing.
