HP Printer Model Number Meaning [Quick Guide] – What Does This Mean on an HP Printer?

It is no secret that the model number of HP printers can be very confusing. Therefore, in this section, we will explain the meaning of HP printer model numbers.

HP started naming its printers starting from the HP LaserJet I series. At this point, the printers were named using the Roman numeral system. After the HP LaserJet I series came the HP LaserJet II series.

A variant of the HP LaserJet II was manufactured and it was named the HP LaserJet IID. The letter “D” represented the duplex printing feature the variant possessed which the original lacked. The letter “D” will go on to become the standard addition to HP printer names with the duplex printing feature.

The HP LaserJet IIID was released next, followed by the HP LaserJet IIP (another variant of the HP LaserJet II), and the HP LaserJet IIIP (a variant of the HP LaserJet IIID). The letter “P” added to the names of these variants indicates that these printers were personal printers.    

After these personal printers, the HP LaserJet IIISI (another variant of the HP LaserJet IIID) was introduced. The letter “S” is added to show that the printer has a paper stacker installed inside it.

At this point, HP dropped the system of using the Roman numeral and started using plain numbers. The first printer that followed this new system was the HP LaserJet 4 series.

Subsequently, the HP LaserJet 4M was released and designed specifically for Macintosh operating systems. This printer had a Postscript Module and was designed with additional memory. From that time, the letter “M” in HP printer model numbers indicates the printer’s Mac or Postscript printing ability.

A variant of the LaserJet 4 series was released later on and was called the HP LaserJet 4L; with the letter “L” being a description for light duty (it had just 1 paper input tray).

The next series was the LaserJet 5 series, and the HP LaserJet 5N was the first printer with an installed network option. So, the letter “N” represents printers with this network option. Eventually, the single-digit model number stopped at the LaserJet 6 series.  

After the 6 series, HP adopted a four-digit numbering system. The reason for this was to provide room for improvement or expansion of a particular model. For instance, the HP LaserJet 4000 series, had the HP LaserJet 4000T which was designed with two trays. The letter “T” shows that the printer has more paper input trays.

When the wireless printing feature was introduced, printers with this feature had the letter “W” added to the model numbers.

When the stapler/stacker option was introduced, printers with this feature had the letter “SL” added to the model numbers. Some printers have more than one feature, so they have more alpha descriptions attached to the model numbers.

You can check out the table below for a tabular description of this alpha system.
