Our take
HP maps U.S. product Q3703A#ABA to the Color LaserJet 2550Ln and marks it discontinued. The exact Ln model adds an internal Jetdirect 10/100 network server to the series' color print engine, with USB and parallel interfaces and a 125-sheet multipurpose tray. HP's series guide rates monochrome output up to 20 ppm Letter and color at 4 ppm. Additional trays are optional and belong to distinct packages. No recommended monthly range is established in the reviewed sources. This is a legacy wired color option for modest needs, not a fast contemporary shared printer.
A low-demand wired color printer where the exact older unit, driver path and supplies have been checked..
Avoid it for frequent color runs, automatic duplex, built-in Wi-Fi, current production support or a high-volume recommendation.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HP identifies the exact U.S. part as Q3703A#ABA and confirms discontinued status.
- The Ln configuration has an internal Jetdirect network server for wired sharing.
- The 125-sheet tray and parallel/USB connections are documented for the series base.
What to weigh up
- HP rates color output at only 4 ppm, which limits longer color jobs.
- No recommended monthly volume is established in the reviewed sources.
- Optional 250- and 500-sheet trays are not standard on the Ln configuration.

What the features mean for you
The Ln suffix marks the networked series configuration
HP identifies product Q3703A#ABA as the Color LaserJet 2550Ln. The series guide says the 2550Ln adds an internal Jetdirect print server to the base 2550L feature set; it does not inherit the 2550n's included 250-sheet tray. That suffix distinction matters when a used listing groups several 2550 variants together. The model prints color and black pages but does not provide copy, scan or fax. Check the exact product number on the unit and do not transfer another 2550 package's included tray or network options.
Color is available, but the rated pace is modest
HP rates the 2550 series up to 20 ppm for monochrome Letter pages, 19 ppm A4 and 4 ppm for color Letter or A4. That large gap matters if color work is frequent: slides, graphics and marked-up documents will take longer than a black text queue. The speed figures are manufacturer ratings, not measured results for an aged unit. The reviewed exact sources provide no recommended monthly range, so this profile does not label the printer for a guessed workload. Occasional color output is a more plausible fit than a room serving regular high-volume jobs.
Use the standard tray and optional trays accurately
HP's series guide lists a 125-sheet multipurpose tray as standard on all 2550 series configurations. It describes optional 250-sheet and 500-sheet trays, but those are separate accessories, and the order of installation matters for the larger option. The 2550n includes a 250-sheet tray; the 2550Ln does not. A seller may bundle extra hardware, but the model name alone cannot establish that. Check each tray's presence, paper pickup and capacity before comparing a used unit with a newer printer whose larger feed is part of its base configuration.
Ethernet is wired Jetdirect, not Wi-Fi
The 2550Ln includes an internal HP Jetdirect print server with a 10/100Base-T port. HP also documents USB and parallel interfaces for the series. The reviewed exact sources do not list built-in wireless, so this is a wired network model rather than a Wi-Fi printer. That can still work in a shared office with a switch and a compatible driver, but it limits flexible placement. Confirm that current computers can use an available driver and that the network configuration is accepted before making a legacy printer a shared dependency.
No automatic duplex is established for this unit
HP's exact 2550Ln configuration guide lists its print engine, tray and network hardware but does not list an automatic duplexer. This review therefore treats automatic duplex as absent for matching rather than borrowing an option from another product. The sources also do not settle a manual two-sided process for the exact unit, so that attribute remains unknown. If double-sided documents are routine, choose a model with clearly documented automatic duplex. For occasional simplex color output, the Ln's wired network feature may matter more than a capability its source set does not prove.
Discontinued status makes condition and support central
HP marks Q3703A#ABA discontinued. Before using a 2550Ln, inspect its color registration, pickup, fuser and network port, and verify that replacement cartridges and a compatible driver can be obtained through current channels. A decades-old spec sheet does not say what condition an offered unit is in, whether supplies are included or whether an old warranty remains active. The article does not make any current price, stock or hands-on claim. If reliable modern support and regular color speed are priorities, compare a current model with the actual total workflow rather than buying on the legacy name alone.
What else to compare
Choose a current wireless color printer for flexible placement or a duplex model for routine two-sided documents.

The decision
The 2550Ln's useful distinction is wired Jetdirect sharing on a legacy color printer. Slow color output, optional tray accessories and discontinued status limit its fit.
