Our take
The HP LaserJet Enterprise M605n is a fast monochrome printer for a wired office queue. HP rates it up to 58 pages per minute on Letter paper and recommends a monthly workload of 5,000 to 16,000 pages. The standard feed includes a 100-sheet multipurpose tray and 500-sheet main tray; Gigabit Ethernet and USB are documented. The n configuration does not include automatic duplex, unlike higher suffixes that add that hardware. Wi-Fi is also an optional accessory. This is a focused, legacy enterprise printer, so the high workload guidance should be weighed against age, current computer support, maintenance history, and the condition of any offered unit.
A wired enterprise office needing high-volume monochrome output and separate scanning, without standard automatic duplex as a hard requirement..
It is not for users who require automatic duplex or built-in Wi-Fi out of the box, or who need copy, scan, fax, or color.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HP rates the mono engine up to 58 ppm Letter and recommends 5,000–16,000 pages monthly.
- Gigabit Ethernet, USB and 600 sheets of standard input support a shared wired queue.
- The exact n suffix makes the configuration's duplex limitation explicit.
What to weigh up
- Automatic duplex is not standard on the M605n; do not borrow features from M605dn or M605x.
- Wireless requires an optional accessory rather than being built in.
- As a discontinued enterprise model, it needs careful checks for support, parts and individual-unit condition.

What the features mean for you
High output for a monochrome workgroup
HP rates the M605 family up to 58 pages per minute on Letter paper and documents a recommended monthly range of 5,000 to 16,000 pages. That makes the printer a candidate for a department with sustained mono output rather than occasional home documents. Speed ratings are comparison points, not promises for every job. The actual pace depends on job content, warm-up, connection, maintenance and device condition. The monthly range is guidance, not a guaranteed lifecycle or replacement for a service plan. HP's U.S. support record anchors these facts to the M605 configuration ([HP M605n specifications](https://support.hp.com/us-en/product/product-specs/hp/model/7087292)).
The n model does not include the duplexer
HP distinguishes the M605n from M605 configurations with other suffixes. Automatic duplex is not standard on the n model, and the duplexer appears on a higher configuration or as optional equipment. For a team that prints one-sided memos, the base setup may be adequate; for repeat two-sided reports, staff will handle the pages manually unless the correct accessory is installed. Confirm both suffix and included hardware from a configuration page before purchase. The printer can be a fast engine and still fail a requirement for automatic duplex, so keep this criterion separate from its headline speed.
Standard input for longer runs
The documented standard arrangement uses a 100-sheet multipurpose tray and a 500-sheet main tray. That 600-sheet total reduces interruptions when a shared queue has a steady paper stream, while a separate feed can be useful for occasional media. The tray count does not establish any optional drawers, which should be counted only if physically included. Match supported sizes and media to the intended jobs and inspect the feed path on a used device. Capacity complements HP's recommended monthly range, but it cannot tell us whether the machine has received maintenance or how long its components will last.
Wired connection and optional Wi-Fi
Gigabit Ethernet and USB are listed for the M605n. A wired network can serve multiple users, while USB provides a local route. Wireless is an optional accessory, not a built-in feature to assume from an M605 family listing. Confirm the accessory's exact compatibility and whether the seller includes it if a wireless setup matters. Because this is an older enterprise unit, verify current driver support, network authentication and security expectations before installing it in a managed office. A working Ethernet port on the brochure is not a guarantee of successful configuration on a present-day network.
A legacy enterprise choice needs inspection
The M605n has a substantial historical feature profile but is marked discontinued by HP. That means a buyer should consider supply availability, parts, firmware and the organization's ability to service it. Ask for the page count, maintenance history, a clean test page, and confirmation that the expected trays and accessories are included. Check the n suffix because M605dn and M605x add different hardware. The manufacturer recommendation describes an appropriate workload class, not the remaining life of a refurbished unit. Do not use a live marketplace listing or its seller claims as proof of technical condition.
When it makes sense to shortlist
The M605n is most coherent for a wired office with substantial black-and-white volume that can work without included automatic duplex and built-in Wi-Fi. Separate capture equipment is required because this model is print-only. For a buyer who values current support, automatic duplex or a smaller desktop footprint more than enterprise speed, another model is a better starting point. Confirm the full model number, installed interface and printer condition, and make a support plan before relying on it. This recommendation is based on HP's documented product facts, not personal testing or a promise about present supply.
What else to compare
Compare M605dn or M605x only after confirming their added hardware, or choose a supported current model if service and drivers are priorities.
Before you buy
Does the M605n print automatically on both sides?
No. HP specifies that the M605n configuration does not include the standard duplexer fitted to other suffixes.
Does it include Wi-Fi?
No built-in wireless is documented; HP lists Wi-Fi as an optional accessory for this Enterprise family.
What speed and workload are published?
HP rates output up to 58 ppm Letter and recommends 5,000 to 16,000 pages per month.
Can it scan or copy?
No. The M605n is a single-function monochrome printer, so capture work needs separate equipment.
