Your needs, this model
Does it fit your priorities?
Can it print ordinary color Legal pages over Ethernet with 300 sheets?
Yes, with Tray 2 extended, correct paper settings and compatible software.
Explore this need in the finder →Does it have automatic duplex hardware?
Yes, under the supported media and software conditions; exact size-specific limits still need checking.
Explore this need in the finder →Does the base configuration include Wi-Fi?
No. That requires the optional Jetdirect accessory and configuration.

The HP Color LaserJet Enterprise M455dn is a color print-only model with automatic two-sided output, USB and Ethernet. Its standard paper supply is a 250-sheet cassette plus a 50-sheet multipurpose tray. That is the useful starting configuration for an office comparison.
An optional larger cassette changes capacity and the physical installation, but is not part of every offer. Decide whether the standard sources cover the work repeated through the week before planning around the maximum expandable setup.
Legal paper changes the space needed in front
The operating guide requires extending the main tray for Legal paper. It projects beyond the ordinary closed position, so a shelf that fits the closed cabinet may not provide comfortable access for longer forms.
Check the actual paper size, guides and software settings when switching stock. Different sources can keep suitable materials ready, but agreed defaults help a shared queue avoid pulling the wrong paper for the next person.
Envelopes have a separate instructed routine using the correct size, type and manual-feed selection. The guide requires clearing the two-sided option for that job. Specialty materials should not be treated as ordinary duplex stock simply because they fit a tray.
Automatic duplex helps ordinary reports
The M455dn includes automatic two-sided printing hardware. That can reduce repeated hand-turning for supported reports. Set the binding deliberately and check a short complete document, including any covers or mixed orientations, before running a larger batch.
Confirm the precise media conditions for the intended job. A broad single-sided paper range and an automatic duplex label are separate pieces of information. The useful result comes from the complete supported combination of stock, settings and software.
Wired connections are included; wireless is an accessory decision
USB and Ethernet provide the supplied desktop and network paths. WiFi, Direct and related mobile features use an optional Jetdirect accessory. Verify the correct installed hardware and supported configuration if cable-free placement matters.
For a shared queue, check current driver support on the actual computers and test representative multipage files. Include reconnection after a restart rather than relying only on the printer appearing in discovery. The walk-up memory-device port is a different path from computer USB.
The color display is operated through its keypad rather than touch. It provides printer controls, but the machine has no scanning glass, document feeder, copying or fax. Incoming paper capture needs another device or a multifunction alternative.
Check the actual private-job and supply arrangements
The guide describes stored and personal jobs through supported desktop software, including a USB-flash storage routine. If confidential release matters, confirm the required storage and settings on the actual unit, then test holding and releasing a document. The built-in memory description alone does not establish every storage workflow.
Consumable compatibility is another purchase consideration. HP describes a requirement for cartridges with a new or reused HP chip and firmware behavior affecting other chips. Compare the exact compatible supply arrangement rather than assuming any similarly described replacement will work.
Use the current US declaration and recurring workload guidance
The current exact US product page declares up to 28 Letter pages per minute for monochrome and color. That is a manufacturer figure rather than our measured timing result. Short jobs, waking and complex layouts affect the practical wait.
The recommended monthly range is intended for recurring workload planning. Include peak batches, paper changes and output collection in the comparison. Inspect the exact model and electrical plate, installed supplies, feeding and representative color output. Leave tray, cover and cable access, then choose this configuration when its compatible wired color routine fits the office.

Paper, software and setup details
Print-rate conditions
The current exact US manufacturer page declares 28 Letter pages per minute in monochrome and color; the original guide says 29. The conservative US figure is used. Recommended monthly output is 900–4,800 pages. No measured speed is claimed.
Paper handling
Supplied input is 50 + 250 sheets. Legal paper requires extending Tray 2 by about two inches. A 550-sheet cassette is optional. Automatic duplex hardware is included, but its exact paper-specific range is unconfirmed here. Envelopes use the instructed one-sided, correct size/type routine.
Scanning arrangement
Print-only equipment, without a scanner, copying glass, document feeder or fax.
Computer and mobile connections
USB and Gigabit Ethernet are supplied. Wi-Fi, Direct, BLE and NFC require the appropriate optional Jetdirect accessory. A walk-up host socket is not the computer USB connection.
Supplies and declared yields
HP describes a new or reused HP chip requirement and firmware behavior affecting other cartridges. Check exact compatible regional 416A/416X supplies; declared yield does not establish current cost or remaining toner.
Software and support
The exact guide lists 1 GB memory, 4 GB eMMC and a non-touch keypad display. Its private-job chapter describes USB-flash storage; required storage and configuration must be verified before assuming PIN release.
Electrical edition and setup
Current US manufacturer reference, without a stock claim. Closed body: 16.28 × 18.59 × 11.98 inches; 41.67 lb with cartridges. Legal tray extension and open covers need more space. Check the actual electrical plate and accessories.
