The LaserJet 4000 series, like most of Hewlett-Packard's laser printer series, follow the standard nomenclature for denoting factory-included features. n = network ready t = twin/two (smaller in some models) paper trays d = duplex/double sided printing s = stacker for output tray l = stapler.
JetDirectJetDirect is a line of external print servers formerly sold by Hewlett-Packard (HP). The JetDirect allows computer printers to be directly attached to a local area network. HistoryProtocolsMore advanced versions of JetDirect supported a number of network printing protocols. However, the protocol that ended up being associated with it, the JetDirect protocol, is its raw TCP/IP protocol sometimes referred to as Socket API or RAW.
Duplex printingDuplex printing is a feature of some computer printers and multi-function printers (MFPs) that allows the printing of a sheet of paper on both sides automatically. Print devices without this capability can only print on a single side of paper, sometimes called single-sided printing or simplex printing. Consumer and low-to-medium volume office printers use a duplexing unit that reverses a piece of paper after the first side has been printed.
Laser printingElectrostatic digital printing process HP LaserJet 4200 series printer, installed atop additional 500-sheet paper tray Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image.
