 series.

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 = two (smaller in some models) paper trays
  • d = double sided printing
  • s = stacker for output tray
  • l = stapler.


Further accessories could also be purchased if the desired functions didn't come factory fitted on the model purchased. For example, network cards, additional trays and duplexing units are the most commonly found.

LaserJet 4000

The LaserJet 4000/4050 and their respective variants were the first printers released in the 4000 series. The LaserJet 4000 series printers print letter paper at 17 pages per minute, and can be set to print at 600 dpi or 1200 dpi, although when set to print at true 1200 dpi, the printer runs at reduced speed. These printers may be connected to a computer using either the serial port

LaserJet 4100

The HP LaserJet 4100 series were replacements for the HP LaserJet 4000/4050 series of printers. The LaserJet 4100 series printers print letter paper at 25 pages per minute, and can be set to print at 600 dpi or 1200 dpi. Unlike the 4000 and 4050 series, the 4100 series printers are capable of printing at true 1200 dpi at full engine speed. These printers may be connected to a computer using either the serial port
