(laserjet) is a brand name that identifies laser printers marketed by the American
computer-company Hewlett-Packard (HP). Many other manufactures make laser printers,
but it is HP that market the LaserJet range.
Each LaserJet has a model number pre-fix
(e.g. 4100 or P3005) and suffixes to identify printers with factory-installed options
(e.g. 4250DTNSL or P2015N).
These suffixes include:
D for a duplexer, a device which enables
fully automatic, hands-free double-sided printing.
T for an additional paper-tray (enables two different paper types to be
kept available, or in certain models, to load paper while the printer is printing). (Some
D models, with no T suffix, had two trays built in, as did the LaserJet 500 Plus.)
S for a Stacker or Stapler/Stacker
N for built-in, MIO or EIO slot JetDirect (network) card
W for built-in wireless network card
H for High-capacity (heavy-duty model, sometimes combined with M to
indicate Heavy Media)
L for Light (only 1 paper tray)
P for Personal, meant for "personal or small workgroup" use
M for Macintosh (PostScript module present); (sometimes?) also extra
memory to support PostScript (as in 4M/4M Plus)
X for combination duplexing, networkable printer with additional tray.
Replaced the DTN suffix.
