Hewlett Pacakard Laser Printer Nomenclature


HP began naming there printer’s in a logical way. The HP Laserjet or HP Laserjet I series dependent on the Canon CX print engine. I consider there is just one in the Smithsonian (not in use however). Relocating forward with the upcoming model was the Laserjet II collection, primarily based on the Canon SX print engine. This collection was also readily available with two enter cassettes. The was the Laserjet IID, based on the Canon TX print motor. The (D) was now the identifier for the duplex (double-sided) printing feature or solution in the model identify. Up coming in the series was the Laserjet IIID, based mostly on the very same canon TX print engine but had now incorporated HP’s Resolution Improvement Technological innovation or RET. In a nutshell using a 300×300 d.p.i. (dots per inch) printer and supplying it 600×600 d.p.i. top quality output.

Mainly just splitting the dot with software (firmware) on the formatter. However only a legitimate 300 d.p.i. printer. This RET technology is nonetheless remaining made use of these days with true 600 d.p.i. printer’s manufacturing 1200 d.p.i. good quality output. In maintaining with employing the Roman numeral numbering there was the Laserjet IIP and IIIP, based mostly on the Canon LX print engine. The (P) in the product was utilized to designate the printer as a own printer. Next in line was the the Laserjet IIISI based on the canon NX print engine. The (S) was used to designate that a paper stacker was resident in the printer.

As printer styles developed and distinct print engines were being remaining utilized HP commenced making use of plain numbering in its place of the Roman numerals. In keeping with the alpha sequence the Laserjet 4 sequence was future. The Laserjet 4M was released for use with the Macintosh operating systems. Incorporated into the printer was a Postscript module and possibly some added memory as properly to aid the additional complicated printer language. The (M) was now applied to designate for use with Mac’s or Postscript printing. Another model in the 4 collection was the 4L, the (L) was made use of as the designation for gentle responsibility (only 1 paper tray). The series continued shifting up to amount 5. The Laserjet 5N, where by (N) was now employed to show a community possibility was put in. The single digit design quantities ended with the 6 collection.

HP then moved to a four digit product numbering program. This would allow the similar product or model to be expanded within the sequence, this sort of as the Laserjet 4000 collection. The 4000T design incorporated two trays. The (T) would now be utilised to show that two or much more paper trays(cassettes) ended up present. Products would use the exact same print engine, but with some included features, these kinds of as a speedier processor or diverse firmware. They were ready to boost the pages for every moment.

HP also released a wireless printing attribute. This would require a wireless community on the host or personal computer as very well. It seamed to be a shorter lived solution. The (W) was applied for this wireless element. A stapler/stacker selection was also released, notated by (SL). For instance: a 4250 DTNSL would have a duplexer, network abilities and a stapler/stacker product as perfectly. The latest printer styles are now using the (X) for the mixture of duplexing, community capabilities together with additional input and output choices. For the most portion HP has ongoing to use a ton of there solution notations.
