In an attempt to further streamline their laser printer branding identification, HP has gone beyond just the LaserJet Color LaserJet branding, incorporating a new sub-branding system.
Knowing the complete model number is very important, since the letters before and after the printer model number will help in determining what printer you have and
the exact parts you need.
The new sub-brands are:
HP LaserJet/Color LaserJet –
designed for all size businesses
HP LaserJet Professional/Color
LaserJet Professional – Designed for Micro and Small sized businesses
HP LaserJet Enterprise/ Color LaserJet
Enterprise – Designed for Medium and Large businesses
HP has also quietly revamped its naming structure to better define the printers’ main function. Originally, HP put the descriptor at the end of the model number (4345mfp). Then, the company changed to a transitional part number with descriptors at both the beginning and the end of the model number (M4345mfp). Now, the newest revision from HP is just a descriptor at the beginning of the model number (i.e. M4555).
Original – LaserJet 4345mfp
Transitional – LaserJet M4345mfp
New – LaserJet M4555
Several letters can be at the end of the model number; these letters will indicate various accessories, options and capabilities.

Remember, knowing these numbers and letters are important. A P3015 is very different than a 3015AiO (all in one) and knowing that will make sure you’re getting the correct parts and troubleshooting information.
