We reviewed the base model of HP's 2550 series, which includes only a 125-sheet multipurpose tray that flips open from the front panel of the printer. You can add either a 250-sheet input tray for $149 or a 500-sheet input tray for $299. (Both are available from HP.) The back panel of the HP 2550L also flips open to create a straight paper path for printing heavier paper stocks.
For connectivity, the HP 2550L provides only a parallel port or a USB 2.0 connection (cables not included). If you want internal networking, you should buy either the HP 2550Ln or HP 2550n models. If you don't need networking now but suspect you might in the future, the 2550L is compatible with several HP Jetdirect external print servers that range in price from $129 to $269 from HP. The printer comes with HP PCL 6 and HP PostScript 3 emulation built in, so documents print looking the same way they do on your computer monitor.As we mentioned earlier, the HP Color LaserJet 2550L has no control panel LCD. To change print settings, you'll need to use HP's LaserJet Toolbox, software that installs on your computer along with the drivers. Toolbox uses a simple Web browser interface and gives you or your network administrator access to printer status information (including toner levels and usage data), troubleshooting tips and demos, and an alerts feature that you can set to send e-mail. The 2550L's drivers are quite basic and easy to use. A series of tabs control such settings as paper size and orientation, document scaling, and the ability to print all text as black. The color tab lets you change the composition of neutral grays between black and four-color as well as half-toning, RGB color, and edge control. For color experts, such as designers and photographers, the 2550L's color settings may be a bit rudimentary compared with those offered on the Samsung CLP-550, but the average user should be satisfied with the available tweaks and the printer's native color-matching capabilities.
The HP 2550L's printing costs are quite reasonable. New 4,000-sheet cyan, magenta, and yellow toner cartridges cost $100. A 4,000-sheet black cartridge costs $83. Estimating 5 percent coverage, this works out to 2 cents per page for black ink and about 2.5 cents per page for color--about average for a color laser printer.Overall, the HP Color LaserJet 2550L was a smooth performer in CNET Labs' tests. The test unit was also very quiet during operation.
For monochrome printing, the HP Color LaserJet 2550L performed well, averaging 12.1 pages per minute (ppm) for text and 9.8ppm for graphics. These scores are above average for a bargain color laser printer. In color printing, on the other hand, the HP was rather disappointing. It averaged only 3.9ppm for text and 3.1ppm for graphics, making the HP Color LaserJet 2550 the slowest in our charts--a surprise, since one of our fastest color laser printers is the HP LaserJet 3500, with a score of 7ppm for color text and 8.8ppm for color graphics.
Making up for its not-so-great speed, however, the HP Color LaserJet 2550L offers excellent monochrome print quality. Both text and graphics looked perfect in our tests, with nary a flaw. The color print quality, though not perfect, was very good as well. Our only nitpick was the contrast, which was a little too soft in color text and a little too harsh in color graphics.
The printer was tested at the factory default settings, which you can adjust to improve the output and performance. Learn more about how CNET Labs tests printers.
