Enhance your work documents with HP’s most

affordable color laser printer in a simple-to-use design.

Remarkably affordable

• Experience a printer that’s easy to use and easy on your

budget. With an amazingly low price and low cost-per-
page, this is your one and only printer for everyday black
and white documents and color promotional material.

• Get high performance with cost-effective sharing. Choose

the connection that suits your small business needs.
Directly connect your printer to your computer with

Hi-Speed USB 2.0 and 1284-B parallel ports standard on
all models, or share the printer among a small workgroup
with HP Jetdirect network connectivity (standard on
HP Color LaserJet 2550Ln and 2550n printers).

• Take advantage of compatibility. HP PCL 6 and

HP postscript level 3 emulation print drivers offer
consistent, professional results. With support for a variety
of Windows and Macintosh operating systems, fitting the
printer into your existing environment is easy.

User

Radically simple

• Replace supplies effortlessly. Get easy access to supplies

with a convenient front door. When a print cartridge
needs to be replaced, it automatically cycles to the top

carousel position—you can then quickly and confidently
replace the proper cartridge with one hand.

• Manage and configure printer functions. HP Toolbox

provides one location where you can view and change
printer settings and access self-help information,
troubleshooting tips, and online documentation.

• View supplies information instantly. The easy-to-understand

control panel takes the guesswork out of determining the
status of your supplies. Plus, HP Smart printing technology

monitors the status of your supplies and provides alert

notifications and ordering information when supplies run
low, allowing you to make proactive ordering decisions.

Impressive results

• Create great-looking documents and images. Print vibrant

color documents and business-quality images with
HP ImageREt 2400 (Resolution Enhancement technology).
HP ImageREt 2400 includes an advanced toner formula
and new HP-engineered fuser technology to provide sharp

text and graphics and consistent color quality over the life
of the printer.

• Reduce time waiting for your documents. Improve business

productivity with speeds of up to 20 pages per minute
(ppm) black and up to 4 ppm color. Instant-on Technology
virtually eliminates printer warm-up time and makes it
possible to print an entire document in the time that it takes
competing printers to warm up.

• Print complex documents gracefully. With a 264 MHz

processor and standard 64 MB RAM, expandable to

192 MB with the industry-standard DIMM slot, the printer
effortlessly processes even the most complex print jobs.

• Depend on flexible media handling. The printer offers

versatile paper-handling options. With a standard
125-sheet multipurpose tray and optional 250-sheet and
500-sheet trays, you can configure the printer to meet your
business needs.


HP printing and imaging systems help you create powerful,
professional communications easily. The printer’s supplies,
accessories, and services are designed to work together and
are invented to meet your business needs.
