HP LaserJet 4000 series


The LaserJet 4000 series is Hewlett-Packard's medium-duty monochrome laser printer range and the successor to the LaserJet 5 series.
The LaserJet 4000 series, like most of Hewlett-Packard's laser printer series, follow the standard nomenclature for denoting factory-included features.
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, parallel port or Ethernet. The LaserJet 4000 series was introduced in November 1997 and was discontinued in May 1999. They are powered by a NEC VR4300 CPU

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, parallel port or Ethernet. The LaserJet 4100 series was introduced in March 2001 and was discontinued in February 2003. The 4100MFP, however, was introduced in March 2002, and discontinued in August 2006. They are all powered by a PMC-Sierra RM5261 CPU

1 = 4200 and 4200dtn were discontinued in November 2005, all other models were discontinued in June 2005

2 = 4240 model is essentially identical to both the 4250 and 4350 models; firmware or microcode on formatter board and/or motor controller board is different so that the printer will not allow the use of
"42X" toners; only lower capacity toners, such as the "42A" are permitted. Printing speed is specified as 3 pages/minute slower than the 4250.
