Our take
HP's LaserJet Enterprise M604dn is a monochrome print-only printer for a busy wired office. HP identifies the U.S. configuration as product E6B68A#BGJ and rates it up to 52 pages per minute on Letter. The standard M604dn includes automatic duplex, a 100-sheet multipurpose tray, and a 500-sheet main tray. HP recommends a monthly range of 5,000–13,000 pages. Gigabit Ethernet is standard, while wireless requires an optional accessory. HP marks the product discontinued. These features suit a department with recurring high-volume text output, but current service and supply needs plus the exact configuration should be checked carefully on any offer.
A wired office queue that needs fast black output and automatic duplex for several thousand pages each month..
Choose a current wireless all-in-one or lower-volume printer if you need copy, scan, built-in Wi-Fi, a compact footprint, or confirmed ongoing manufacturer support.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HP rates the M604dn up to 52 ppm Letter and recommends 5,000–13,000 pages monthly.
- The exact dn configuration includes automatic duplex and 600 sheets of standard input across two trays.
- Gigabit Ethernet and USB provide documented standard paths for a wired shared queue or direct connection.
What to weigh up
- HP marks the M604dn discontinued, so service, drivers, parts, and supplies need separate current checks.
- The standard configuration has no built-in wireless; the optional adapter should not be assumed to accompany a used unit.
- This is print-only and monochrome, so offices needing color, scanning, or fax require additional devices.

What the features mean for you
Does the exact M604dn configuration fit?
The U.S. product page maps E6B68A#BGJ to the M604dn. That exact part is important because an earlier candidate clue used a different suffix that was not reconciled to the U.S. unit. HP's record lists the dn configuration as monochrome print-only and includes an automatic duplexer. Match the chassis label and product code rather than relying on a title that says only M604. If the seller cannot show the exact part, keep the standard configuration uncertain until the unit can be checked; family-level facts should not migrate between nearby n and dn variants.
How do speed and paper capacity serve a workgroup?
HP rates Letter output up to 52 pages per minute and lists a 100-sheet multipurpose tray with a 500-sheet main tray. This provides a larger standard paper reserve than a compact personal printer, while the speed rating describes a top capability, not a guaranteed time for a complex job. Automatic duplex supports two-sided packets without manual reloading. For teams that routinely print thousands of pages, HP's 5,000–13,000 monthly recommendation gives the more useful fit range. Consider whether two trays are enough for the office's stocks and whether a used device retains both trays.
What connection can the office rely on?
HP lists a built-in Gigabit Ethernet network port and USB as standard. Ethernet fits a wired office queue where the printer can connect to a managed network. Wireless is optional rather than a normal part of the M604dn configuration. An optional accessory could enable that route on a specific unit, but the model name alone does not prove that it was purchased or remains installed. If the printer will sit outside wired coverage, verify the accessory's identity and operation or choose a product with built-in wireless. A network specification also does not establish current driver compatibility.
Is the workload recommendation appropriate?
HP recommends 5,000–13,000 pages monthly and separately states a much higher maximum duty cycle. The recommended band is the operating guidance to compare with normal monthly use; the maximum is not a safe monthly goal. A team well below the minimum may be paying for capacity it does not need, while a team above the upper recommendation should look for a model intended for heavier routine use. Pair this figure with toner, paper, and maintenance planning rather than relying on speed alone. A printed page count on a used printer is a separate fact that must be checked on that unit.
How should discontinued status affect purchase checks?
HP marks the M604dn discontinued. Its specification remains clear, but present support arrangements, supply availability, firmware status, and condition depend on the particular unit and seller. Check the product number, duplexer, trays, port condition, page count, service history, and return terms. Do not infer current stock or economical ownership from a published speed or cartridge page. A replacement may be a better fit if the office requires an active support channel or needs Wi-Fi without add-on hardware. If choosing this model, make the condition and support review part of procurement.
What else to compare
Compare a current enterprise mono printer if support and a confirmed supply path are required, or a wireless MFP if users also need copy and scan functions.
Before you buy
Does the M604dn print automatically on both sides?
Yes. HP lists an automatic duplexer as standard on the M604dn; the M604n is a separate configuration.
Is built-in Wi-Fi included?
No. HP identifies wireless as optional hardware; Gigabit Ethernet and USB are standard on the M604dn.
What is HP's recommended monthly range?
HP recommends 5,000–13,000 pages monthly. Its maximum duty-cycle figure is a ceiling, not a recommended routine workload.

The decision
The M604dn has a well-defined high-volume wired role with speed, duplex, and standard paper reserve. Its discontinued lifecycle and optional wireless are material purchase trade-offs.
