HP LaserJet 4si Toner Cartridges Printer Review

Expert review of the HP LaserJet 4si printer 14 December 2012

Our Verdict:

The HP LaserJet 4Si is a monochrome laser printer produced during the 90's. This unit has a maximum resolution of 600 x 600 dpi and it delivers good quality texts and greyscale graphics. The printer has a duty cycle of 75,000 pages, while the envelope feeder has a duty cycle of 3,000 pages. Since the HP LaserJet 4Si printer is outdated, it has already been surpassed by newer models in terms of print speed and resolution.


The 4Si printer measures 16.5 x 21.5 x 23.5 inches and measures 123.2 lbs. With optional paper trays, it can handle a maximum of 2,600 sheets. The HP LaserJet 4Si mono laser printer has a parallel port. Print speed can go as fast as 17 ppm. HP have now discontinued cartridges for the HP LaserJet 4Si printer which means that this device now runs on a black Lexmark 140191A cartridge.


First introduced into the market in 1993, the HP LaserJet 4Si monochrome printer is very easy to use and operate. This printer delivers reasonable quality output. It is reliable and requires little maintenance. The HP 4Si LaserJet printer can handle a wide range of media including envelopes, labels, transparencies, and cards plus it has a high duty cycle.


This printer has already been discontinued making it hard to find replacement parts for the HP LaserJet 4Si. The HP 4Si laser printer does not come with standard networking options and it lacks modern connectivity like USB 2.0. There are new printers that can deliver better output than the LaserJet 4Si. For a laser printer, 17 ppm is now considered to be a slow speed.
