HP Color LaserJet 2550 Series Printer - Product Features

This document describes the multiple printer configurations in the HP Color LaserJet 2550 series, as well as the features and benefits the printers provide. Additionally the location and layout of printer components and control panel buttons are discussed below.

Printer configurations

The following sections describe the three different printer configurations.

HP color LaserJet 2550L

The HP color LaserJet 2550L printer is a four-color laser printer that prints letter-size pages up to 20 pages per minute (ppm) in black and white, A4-size pages up to 19 ppm, and it prints letter/A4-size pages at 4 ppm in color. It includes a PCL 6 printer driver and an HP postscript level 3 emulation print driver.

  • Trays . The printer comes with a multipurpose tray (Tray 1) that holds up to 125 sheets of various print media or 10 envelopes. The printer can also accept an optional 250-sheet tray (Tray 2) for standard sizes and optional 500-sheet tray (Tray 3) for A4 and letter sizes. (Optional Tray 2 must be installed in order to install optional Tray 3.)

  • Print cartridges . This model comes standard with color print cartridges (cyan, yellow, and magenta) that can print up to 2,000 pages at 5 percent coverage. It comes with a black print cartridge that can print up to 5,000 pages at 5 percent coverage. (A typical business letter has 5 percent coverage.)

  • Connectivity . The printer provides parallel and universal serial bus (USB) ports for connectivity. The printer also accepts an optional HP Jetdirect external print server for connecting to a network.

  • Memory . The printer comes standard with a 64-megabyte (MB) random access memory (RAM).

  • Expandability . The printer has one available DIMM slot for memory expansion and additional font support. The memory is expandable to 192 MB by adding a 128-MB DIMM.

HP color LaserJet 2550Ln

The HP color LaserJet 2550n printer has the same features as the HP color LaserJet 2550L printer, except it includes an HP Jetdirect internal print server (supporting the TCP/IP protocol only) for connecting to a 10/100Base-T network. This model also accepts optional Tray 2 and optional Tray 3. (Optional Tray 2 must be installed in order to install optional Tray 3.)

HP color LaserJet 2550n

The HP color LaserJet 2550n printer has the same features as the HP color LaserJet 2550Ln printer and also includes Tray 2. This model also accepts optional Tray 3. This model comes standard with high-capacity color print cartridges that can print up to 4,000 pages.

Printer features

The following sections describe the important features of the HP Color LaserJet 2550 series printers.

Color printing

Provides laser printing in full color by using the four process colors: cyan, magenta, yellow, and black (CMYK).

Fast print speed

Prints in black on letter-size paper up to 20 pages per minute (ppm) and on A4-size paper up to 19 ppm. Prints in color on A4/letter at 4 ppm.

Excellent print quality

  • ImageREt 2400 provides 2400 dpi color and laser-class quality through a multilevel printing process.

  • True 600 by 600 dots per inch (dpi) text and graphics.

  • Adjustable settings to optimize print quality.

  • The HP UltraPrecise print cartridge has a finer toner formulation that provides sharper text and graphics.

Ease of use

  • Few supplies to order. Supplies are easy to install.

  • Convenient access to printer information and settings by using the HP Toolbox software.

  • Convenient access to all supplies and to the paper path through the front door.

Expandability

  • Optional Tray 2. (Included with the 2550n model; compatible with all other models.) This 250-sheet tray for standard sizes reduces how often you have to add paper to the printer. Only one 250-sheet tray can be installed on the printer.

  • Optional Tray 3. This 500-sheet tray for letter and A4 sizes reduces how often you have to add paper to the printer. Only one 500-sheet tray can be installed on the printer. Optional Tray 2 must be installed in order to install optional Tray 3.

  • Optional HP Jetdirect external print server for connecting to a network (HP color LaserJet 2550L printer).

  • One DIMM slot for adding memory and fonts.

Flexible paper handling

  • Adjustable Tray 1 (multipurpose tray) for letterhead, envelopes, labels, transparencies, custom-sized media, postcards, glossy paper, HP LaserJet Tough paper, and heavy paper.

  • Optional Tray 2 (250-sheet tray) that is adjustable for several standard sizes of paper.

  • Optional Tray 3 (500-sheet tray) for letter- and A4-size paper. (Optional Tray 2 must be installed in order to install optional Tray 3.)

  • One 125-sheet output bin and one output door. Select the top output bin (face down) for most jobs, including transparencies. Use the rear output door (face up) for jobs on heavy paper, light paper, or special print media.

  • Straight-through paper path capability from Tray 1 to the rear output door.

  • Manual two-sided printing (duplexing).

Printer driver features

Fast printing performance, built-in Intellifont and TrueType scaling technologies, built-in HP-GL/2 vector graphics, and advanced imaging capabilities are benefits of the PCL 6 printer language. The PCL 6 also includes 45 scalable TrueType fonts and one bitmapped Line Printer Font. The PCL 6 printer language also included.

HP postscript (PS) level 3 emulation language and fonts

Includes 35 built-in PS language fonts.

Automatic language-switching

The printer automatically determines and switches to the appropriate printer language such as PS or PCL 6) for the print job.

Interface connections

  • Bidirectional enhanced capabilities port (ECP) type-B parallel port (IEEE-1284 compliant).

  • High-speed USB port.

  • Accepts an optional HP Jetdirect external print server (HP color LaserJet 2550L printer). The HP Color LaserJet 2550Ln and 2550n printers include an HP Jetdirect internal print server that supports the TCP/IP protocol only.

Networking

NOTE: The internal print server in the HP Color LaserJet 2550Ln and 2550n model printers support the TCP/IP network protocol only.
  • Accepts an optional HP Jetdirect external print server (HP color LaserJet 2550L printer). The HP Color LaserJet 2550Ln and 2550n printers include an HP Jetdirect internal print server.

  • All common network protocols such as Ethernet, Token Ring, and LocalTalk are available by using an optional HP Jetdirect external print server. (The 2550Ln and 2550n models include an HP Jetdirect internal print server.)

Enhanced memory and memory expansion

The printer comes with 64 MB of memory and can be expanded to 192 MB by using the DIMM slot. Most documents can be printed with the standard amount of printer memory through the aid of Memory Enhancement technology (MEt). MEt automatically compresses data, virtually doubling the printer memory and accommodating more complex printing with available memory.

Energy savings

  • The printer automatically conserves electricity by substantially reducing power consumption when it is not printing.

  • As an ENERGY STAR partner, Hewlett-Packard Company has determined that this product meets ENERGY STAR guidelines for energy efficiency. ENERGY STAR is a U.S. registered service mark of the United States Environmental Protection Agency.

Economical printing

N-up printing (printing more than one page on a sheet) and two-sided printing using manual duplexing saves paper.

Supplies

  • A Supplies Status page with print cartridge and imaging drum gauges that show the supply levels that remain. For HP supplies only.

  • No-shake cartridge design.

  • Authentication for HP print cartridges.

  • Enabled supplies-ordering capability.

Accessibility

  • Online user guide that is compatible with text screen-readers.

  • Print cartridges and the imaging drum can be installed and removed by using one hand.

  • All doors and covers can be opened by using one hand.
