Our take
HP's U.S. store identifies the Color LaserJet 3550n as product Q5991A#ABA and marks it discontinued. HP's series specification lists color laser output up to 16 pages per minute at 600 x 600 dpi. HP's setup guide distinguishes the 3550n as the model that connects to a network. The sources reviewed here do not establish a recommended monthly range, built-in Wi-Fi, or standard automatic duplex for this exact configuration, so those points remain unknown. This is best judged as a legacy color printer whose present usefulness depends on an individual device's condition, available supplies, and compatible drivers.
A buyer evaluating a specific older unit who needs color network printing and can verify condition, supplies, and connection compatibility before purchase..
Avoid it if you require current manufacturer support, a documented workload range, confirmed automatic duplex, Wi-Fi, or a machine whose condition and consumable availability can be assumed from the model name.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HP's U.S. page maps the exact 3550n name to product Q5991A#ABA.
- The series specification gives a 16 ppm rated pace and 600 x 600 dpi resolution.
- HP's guide treats the 3550n as the network-connected configuration.
What to weigh up
- HP marks this model discontinued, so the name alone does not establish present support or available supplies.
- The checked sources do not establish a recommended monthly print range.
- Automatic duplex and built-in Wi-Fi are not confirmed for this exact configuration.

Full review: how the features affect your choice
What the features mean for you
Verify the part before comparing listings
HP's U.S. store page identifies the model as Color LaserJet 3550n, product Q5991A#ABA, and marks it discontinued. Those details help distinguish it from nearby 3500 and 3550 family listings. A used marketplace title is not proof that the item matches this exact suffix or part. Check the machine's label and included components, then compare them with the intended replacement supplies and driver package. A discontinued flag is not by itself a verdict on a working unit, but it makes condition and ongoing support questions central to the decision.
A modest rated pace for color output
HP's series specification gives a maximum listed speed of 16 pages per minute and 600 x 600 dpi output. The rating offers a way to compare the 3550n with other color devices, but actual jobs vary with content, connection, and print settings. The source does not promise a particular result for a specific document. This type of legacy color printer may make sense for occasional diagrams and office pages when a compatible unit is already available. A busy shared queue should compare its expected volume and wait tolerance against newer options.
Network capability does not mean Wi-Fi
HP's setup guide explicitly separates the 3550n as the model that connects to a network. That supports treating it as a wired network configuration, while the checked exact-model material does not establish built-in Wi-Fi. Confirm the physical port and supported connection method on the actual printer. Networked availability also does not guarantee that it can join a modern managed network or work with a current computer; drivers, print protocols, and administrative rules should be checked independently before relying on it for a shared office.
Do not infer duplex from a family name
The sources reviewed for this exact part do not confirm automatic two-sided printing. The same applies to manual duplex support: if a feature matters, confirm it in an exact configuration guide or on the unit rather than relying on another LaserJet model's options. A print-only device can still be useful for one-sided color work, but regular double-sided output may add staff handling or require another machine. Inspect paper paths and test the offered unit if you are considering a used device; a product specification cannot tell you whether its feed and imaging components still work.
Treat workload guidance as unknown
HP's reviewed series page gives a 45,000-page maximum monthly duty figure, but that is an upper engineering limit rather than a recommended routine volume. No recommended minimum or maximum was established in the checked source packet. Keep both matching values unknown instead of converting the duty ceiling into an everyday workload claim. Estimate the number of pages the device is likely to handle, then consider age, consumable condition, and the cost of keeping an older color system operating. If a model-specific recommendation is essential, seek an exact HP source before choosing it.

The decision
The 3550n is worth evaluating only as an exact, condition-checked legacy unit; its verified color output and network role do not resolve Wi-Fi, duplex, or routine workload fit.
