The HP LaserJet 4000 series represents Hewlett-Packard's lineup of medium-capacity monochrome laser printers, introduced as the successor to the HP LaserJet 5 series.
HP’s naming convention for built-in features in this series is as follows:
- n = network enabled
- t = dual paper trays
- d = duplex printing capability
- s = output tray stacking
- l = stapling function
For models without certain built-in options, extra components such as network cards, additional trays, and duplex units could be purchased separately.
LaserJet 4000
The initial models in the 4000 series were the LaserJet 4000 and 4050 along with their variations. These devices produce letter-sized prints at a rate of 17 pages per minute, offering selectable resolutions of either 600 or 1200 dpi (noting that printing at 1200 dpi slows output). Available interfaces include serial, parallel, and Ethernet connectivity on network-enabled ("N") versions. Launched in November 1997 and phased out by May 1999, these printers operated using a NEC VR4300 processor.

LaserJet 4100
The HP LaserJet 4100 series was introduced as the successor to the LaserJet 4000/4050 line, delivering printing speeds of up to25 pages per minute at either600 dpi or true1200 dpi without sacrificing speed. Released in March2001 and discontinued by February2003 (with the exception of the4100MFP model which remained available until August2006), these printers supported serial, parallel, and Ethernet interfaces on network-enabled versions. The processing unit was a PMC-Sierra RM5261 CPU.

LaserJet 4200
The HP LaserJet 4200 lineup succeeded the LaserJet 4100 series, debuting in December 2002 alongside the LaserJet 4300 series. Most variants were phased out by June 2005, with the exception of the base 4200 and the 4200dtn models, which remained available until November 2005.
This series includes several configurations: 4200, 4200n, 4200tn, 4200dtn, 4200dtns, and 4200dtnsl. The standard model comes equipped with 48 MB of RAM, a parallel interface port, and a paper tray capable of holding 600 sheets. Higher-end versions feature factory-installed enhancements and increased memory of 64 MB.
The series is driven by a PMC-Sierra RM7065A processor running at 300 MHz, based on a 64-bit MIPS architecture. Its print engines are manufactured by Canon. Supported printing languages encompass PCL, PostScript, HP-GL/2, and PJL.
LaserJet 4300
The LaserJet 4300 series delivers faster performance compared to the 4200n models. The available variants are:
- 4300
- 4300n
- 4300tn
- 4300dtn
- 4300dtns
- 4300dtnsl
The entry-level 4300 model includes 64 MB of memory, a parallel port, and a standard tray with a capacity of 600 sheets. Other versions offer an upgraded memory capacity of 80 MB. All models utilize a PMC-Sierra RM7065A CPU operating at 350 MHz—a MIPS-based, 64-bit processor—and support print languages such as PCL, PostScript, HP-GL/2, and PJL.

1Models 4200 and 4200dtn were discontinued in November 2005; all others ended production in June of that year 2The LaserJet 4240 closely resembles the 4250 and 4350 but limits toner cartridge use to lower-capacity options, which results in marginally reduced print speeds.
