Our take
HP's U.S. product page maps product CZ255A#BGJ to the Color LaserJet Enterprise M651n and lists it as a print-only color laser printer. HP rates it up to 45 pages per minute on Letter in both black and color and recommends 2,000 to 17,000 pages per month. The M651n is the wired configuration with Ethernet; wireless requires an optional accessory. HP's specifications distinguish the n model from the M651dn and M651xh: those siblings include automatic duplex, while the M651n handles two-sided printing manually.
A wired commercial color print station for substantial monthly volumes when manual two-sided handling is acceptable..
Choose another printer if color copying or scanning, standard built-in Wi-Fi, or automatic duplex printing is required.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The 45-ppm Letter rating applies to both black and color output on the exact model.
- HP provides a 2,000–17,000-page recommended monthly band rather than only a maximum duty figure.
- Ethernet is documented as standard for a wired commercial installation.
What to weigh up
- The M651n has manual duplex; automatic duplex belongs to the M651dn and M651xh variants.
- The printer does not copy, scan, or fax, and the exact M651n is marked discontinued by HP.
- The 17,000-page upper recommendation may be more than a small desk needs.

What the features mean for you
Keep the M651n separate from its duplex siblings
HP's M651 specification table distinguishes M651n, M651dn, and M651xh by product code and paper-handling equipment. The M651n is the CZ255A configuration; HP lists automatic duplex on the dn and xh variants, not the n. The exact product page describes manual duplex support for the M651n. A suffix check therefore changes whether two-sided jobs involve a user turning pages or a printer mechanism. Do not use a listing for a sibling to fill in the n model's feature set.
Color output without copy or scan functions
HP documents print-only operation and separate black and color print speed of up to 45 pages per minute on Letter. That is useful when the main job is producing color documents for a connected office, but it does not replace a copier, scanner, or fax machine. The speed is a maximum manufacturer rating and should not be treated as the pace for every file, paper type, or duplex job. Workflows that also digitize originals need a separate device or an MFP.
Wire the printer into an office network
HP lists 10/100/1000 Ethernet for the M651n. Wireless networking is optional and is not part of the standard configuration documented for this exact model. That makes a wired deployment the clear setup path when the office can provide a network cable. A buyer who requires built-in Wi-Fi should choose a different configuration or verify the specific optional hardware rather than assuming that an enterprise product includes every connection. HP's page also identifies this model as a commercial-class device.
Size the page workflow and paper installation
HP lists two standard paper trays and a recommended monthly range from 2,000 to 17,000 pages. That broad band points to a shared work setting rather than a low-volume personal printer. The standard trays support different sizes and media weights, but actual tray capacity and any feeder accessories should be confirmed from the exact source and installed configuration. The recommended range is not the same as the maximum duty cycle, and neither figure says anything about the remaining life of a used unit.
Consider the full ownership setup
HP marks the M651n discontinued and notes commercial-environment emissions. Those are manufacturer statements, not a claim about today's used listings. They make it sensible to verify the exact model code, electrical configuration, compatible supplies, driver needs, network policy, and machine condition before selecting a particular unit. The product is most compelling where its rated color throughput and workload range match a real office routine. For a small or occasional workload, a simpler printer may be easier to place and support.
What else to compare
Choose the M651dn when the exact duplex configuration is needed, or an MFP when office documents also need copying and scanning.
Before you buy
Does the M651n automatically print two-sided pages?
No. HP lists manual duplex on the M651n; automatic duplex is standard on separate M651dn and M651xh variants.
Can the M651n copy or scan?
HP identifies the M651n as print-only, so copy and scan functions are not part of this model.
What monthly workload does HP recommend?
HP lists 2,000 to 17,000 pages per month for the M651n and a separate maximum duty cycle.

The decision
The M651n offers documented high-speed color output and a broad workgroup recommendation on Ethernet. Its manual duplex, print-only workflow, and discontinued status deserve careful model-level checks.
