LaserJet 4200

The HP LaserJet 4200 series were replacements for the HP LaserJet 4100 series of printers. They were introduced in December 2002 together with the HP LaserJet 4300 series. All models except the 4200 and 4200dtn were discontinued in June 2005, the latter being discontinued in November 2005. The HP 4200 series of printers consists of the following * 4200 * 4200n * 4200tn * 4200dtn * 4200dtns * 4200dtnsl. The base model, the 4200, has the following specifications: 48 MB of memory, parallel port connection and a 600 sheet paper tray. All the others with factory-installed features as indicated above have 64 MB of memory. They are all powered by a

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" (approx. 20,000 page capacity) toners; only lower capacity toners, such as the "42A" (approx. 10,000 pages) are permitted. Printing speed is specified as 3 pages/minute slower than the 4250.
