Our take
The LaserJet Enterprise M604n is a wired, monochrome printer for a busy office queue. HP's U.S. page identifies the E6B67A#BGJ configuration, rates it up to 52 pages per minute on Letter paper and gives a recommended monthly range of 5,000 to 13,000 pages. That combination offers a clearer workload fit than a speed rating by itself. The base n model includes Ethernet and USB, but HP describes automatic duplex as an add-on, and built-in Wi-Fi is not listed. It is print-only, so scanning, copying and fax remain separate. Its strongest case is fast, higher-volume black output with an intentionally wired installation.
A wired office that needs fast black-only print output at a defined monthly workload and is prepared to verify any optional duplex hardware..
Choose another model if the workflow needs a built-in duplexer, wireless placement, color, scanning or occasional low-volume home use.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HP documents up to 52 ppm Letter and a 5,000–13,000 page monthly recommendation.
- The exact U.S. M604n configuration lists standard Ethernet and USB connections.
- Two standard trays support a more involved shared-office paper routine.
What to weigh up
- Automatic duplex is optional on the base n model and must be verified separately.
- The M604n is monochrome print-only hardware without scanning, copying or fax.
- Built-in wireless is not listed for this U.S. configuration.

What the features mean for you
Use the recommended range to judge workload fit
HP recommends 5,000 to 13,000 pages per month for the U.S. M604n. That makes the model a more natural shortlist choice for an active department than for a desk that prints a handful of pages each week. The range should be compared with the office's typical month, not treated as a goal or warranty. HP also rates the unit at up to 52 pages per minute on Letter paper, a strong headline number for long document queues. Real output depends on job type, settings and device state. The recommendation and speed together describe a workgroup tool; neither one guarantees the condition of an individual used printer.
The M604n is a printer, not a multifunction center
The exact M604n configuration is a single-function monochrome printer. It makes sense where a separate copier or scanner is already available and staff mainly need black forms, reports and internal documents. There is no color output and no fax path from the printer itself. That focus can keep the decision clear, but it also means the unit cannot absorb document capture jobs later. Make a list of the tasks the device must handle before comparing printers: if even occasional scanning at the same desk is mandatory, an MFP is the better category. This listing should not be confused with related M604 models that carry different suffixes and features.
Check for the optional duplexer
HP states that automatic duplex can be added to the M604n; it is not part of the base n configuration. A listing that simply says M604n does not establish that the duplexer is installed. For frequent two-sided jobs, ask for a photo of the rear attachment and a working duplex sample. Without that option, staff may need another workflow for double-sided documents. The n suffix also matters because nearby Enterprise configurations may include different features. Confirm the full product code and installed accessories before comparing the machine against a strict duplex requirement. The catalog marks automatic duplex false for the base configuration and does not upgrade it based on a broad family listing.
Ethernet and USB suit a wired office
HP lists Ethernet and USB interfaces for the M604n. Ethernet can connect a stationary shared printer to a wired office network, while USB remains an option for direct installation. Built-in wireless is not documented for this exact U.S. model, so a wireless-only room needs another plan. Network presence does not guarantee compatibility with the office's policies, print server or operating systems; verify drivers and security requirements before placing the printer in a managed environment. The two standard trays also support handling separate paper supplies, but confirm the exact included trays and their condition on a used unit.
Verify the precise U.S. product and used-unit details
HP identifies the M604n with the U.S. product number E6B67A#BGJ. That is useful because historical and renewed listings can shorten or vary the suffix. Confirm the model plate against the intended electrical configuration, and check whether the optional duplexer and all paper trays are included. A demonstration should cover a print job, the chosen network route and duplexing if that option is part of the purchase. The HP product page cannot confirm a seller's maintenance history, toner state or remaining component life. The exact-model Amazon search is a lookup path, not a live price or stock claim; compare return coverage and service options for the individual offer.
What else to compare
Choose an Enterprise configuration with a documented duplexer if automatic two-sided printing is essential, or an MFP if scanning and copying must be handled at the same device.
