Our take
The Xerox Phaser 5550N is a large monochrome network printer for an office queue where speed and paper capacity matter more than compact size. Xerox rates it up to 50 pages per minute on Letter paper and specifies 1,100 sheets of standard input across a 100-sheet multipurpose tray and two 500-sheet trays. The N configuration includes Gigabit Ethernet, while automatic duplex is an option; Xerox makes it standard on the separate 5550DN. The recommended-volume source says up to 50,000 pages monthly but gives no lower endpoint.
A shared wired office that values fast monochrome output and large standard paper capacity, and can verify or add the optional duplex unit if two-sided printing is needed..
Skip the 5550N if standard automatic duplex, built-in wireless, copy or scan functions, or a known lower monthly recommendation is required.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The manufacturer rates Letter output up to 50 pages per minute for this exact network configuration.
- The 1,100-sheet standard input can reduce replenishment interruptions for a shared queue.
- Gigabit Ethernet provides a documented wired network connection for office use.
What to weigh up
- The 5550N's automatic duplex unit is optional, unlike the standard duplex configuration on 5550DN.
- The recommended monthly volume has an upper endpoint but no published lower threshold in the reviewed source.
- Its office-scale paper capacity and footprint are excessive for many single-desk routines.

Full review: how the features affect your choice
What the features mean for you
Match the published speed to a shared print queue
Xerox rates the Phaser 5550N at up to 50 pages per minute on Letter paper. That figure can help compare its intended pace with slower desktop models, but it is a manufacturer rating rather than a promise for every job, driver, media type or used machine. Mixed graphics, warm-up and print settings change elapsed time. The model is most compelling where several users send recurring monochrome jobs and its rated speed can be used, rather than at a desk that prints a few pages intermittently.
Keep a large paper supply ready
The standard configuration totals 1,100 sheets: 100 sheets in the multipurpose tray and two 500-sheet trays. That amount can keep ordinary paper loaded while leaving another tray available for a different stock, and it reduces refill interruptions in a busy queue. It is not the same as claiming a larger optional feeder is included. Check the precise tray set and feed condition in any used listing because accessories and wear can change what arrives with the printer.
Verify duplex before choosing the N suffix
Xerox's configuration table distinguishes the 5550N from the 5550DN: automatic duplex is optional on the N and standard on the DN. That difference changes both purchasing checks and everyday handling. If two-sided reports are common, verify that the offered 5550N includes the compatible duplex option or compare it with a documented DN unit. A listing that shortens the model name is not enough to establish that the optional assembly is installed.
Use the wired connection the model documents
The U.S. specification identifies Gigabit Ethernet for the 5550N. That supports a shared wired office placement, but the reviewed configuration does not establish built-in wireless. Ethernet can suit a stable network queue; it does not by itself establish that a particular business network, driver policy or operating system will work with an old device today. Confirm local support and the exact port condition before purchase, especially when evaluating a previously deployed unit.
Treat the monthly figure as an upper bound
Xerox states a recommended print volume of up to 50,000 pages per month but does not supply a lower endpoint in the reviewed document. Preserve that asymmetry: the source supports an upper value, not a minimum workload or a claim that any lower number is unsuitable. The maximum-duty wording is a different specification again. This entry therefore does not place the model into a narrow monthly band or call it economical at any usage level.
Compare for your needs
Choose the 5550DN when the standard duplex assembly matters, or a smaller model when an 1,100-sheet office input supply is unnecessary.
