HP LaserJet - Models - Model Suffixes

Model Suffixes

Printers with factory-installed options have different model-numbers to denote the different options included and to differentiate a specific model from others in its series. These suffixes include:

• D for a duplexer, enabling automatic 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 Paper Stacker, a device which increases the output bin capacity.
• 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
• ph+ for Paper handling (e.g. Stapler-stacker), or S/SL for stapler/stacker.
• M for Macintosh (PostScript module present); (sometimes?) also extra memory to support PostScript (as in 4M/4M Plus)
• V for 11-inch wide paper path, to support 8.5x11R and 11"x17" paper. (as in 4MV)
• X for combination duplexing, networkable printer with additional tray. Replaced the DTN suffix.
  • Example: A LaserJet 4000X would come with a duplexer and a built in JetDirect card, as well as an extra paper tray.
