Description
The HP Color LaserJet Enterprise M751dn, product code T3U44A, is a large color laser printer for organizations rather than homes. It prints and does nothing else: the specification lists print only functionality with no scanning, copying or fax. HP specifies media handling up to 12 by 18 inches, three trays, automatic two sided printing, a 1200 x 1200 dpi resolution, 512MB of memory, a color LCD control panel, and Ethernet plus USB connectivity. It weighs a listed 88 pounds and carries a one year next business day onsite warranty.
What Makes This an Enterprise Machine
Three things separate this from an office color laser, and each is worth understanding.
The first is media size. HP lists a maximum media size of 12 by 18 inches. Most office lasers stop at legal, which is 8.5 by 14 inches. A 12 by 18 inch sheet accommodates full bleed tabloid layouts, oversized drawings, signage and proofs. If that capability is why you are looking at this printer, it is the specification that justifies the machine, and nothing cheaper will do it.
The second is the consumable arrangement. The included components list is unusually explicit: the printer, four preinstalled HP LaserJet toner cartridges, four preinstalled HP Original LaserJet imaging drums rated at approximately 65,000 pages each per color, a getting started guide and a power cord. Preinstalled full drums rather than starter cartridges represents real value, and a 65,000 page drum life per color is a workgroup figure. On a color laser you are buying four of everything, and knowing that all eight consumables are in the box changes the arithmetic considerably.
The third is the warranty. HP specifies a one year onsite, next business day warranty as part of the product. Onsite service means an engineer comes to the machine rather than you shipping an 88 pound printer anywhere, which for a device this size is not a small distinction. Confirm the geographic coverage of that service before relying on it.
Print Quality, Security and Power
HP quotes 1200 x 1200 dpi in both color and monochrome, and describes HP JetIntelligence toner along with a special enhanced color mode for a wider range of colors. Those are HP’s own descriptions rather than measured results, and this page does not treat them as tested. What can be said is that 1200 x 1200 dpi is the expected resolution class for an enterprise color laser and is appropriate for business graphics and text.
Security is HP’s other emphasis: the description claims more than 200 embedded security features that detect and stop threats. That framing is marketing language and the specific features are not enumerated on this listing. What is real is that networked printers are a legitimate part of an organization’s attack surface, and enterprise machines do carry firmware verification, encrypted storage and administrative controls that consumer models do not. If security is a purchasing requirement, get the specific feature list from HP rather than relying on a count.
Note the power figure: 870 watts. That is a substantial draw, typical of a color laser fusing at speed, and it is worth accounting for in a small office where several devices share a circuit. Laser printers draw the most power during warm up and fusing rather than at idle.
Paper Handling
The specification block lists three trays with a maximum input sheet capacity of 250. Read that as a base configuration figure, since enterprise printers of this class are typically expandable with additional trays. Automatic two sided printing is included. The maximum copies per run field reads 64, which on a print only device does not describe anything useful.
Print media is listed as plain paper. For a machine capable of 12 by 18 inch output, the range of supported stock weights and finishes matters a great deal, and this listing does not provide it. If you intend to print on heavy or coated stock, get HP’s media specification for this model before committing.

Things To Consider
Size and weight first. At 88 pounds and 21.9 inches deep by 15.7 wide by 23.2 high, this is a floor standing or heavy table machine that needs a planned location and more than one person to install. It is not a desktop printer in any sense.
The specification block contains fields that do not belong to a print only device and should be ignored: a scanner type of “sheetfed”, copy speed and copy resolution entries, and a maximum copies per run figure. There is no scanner or copier on this machine. Note also that the only speed figure anywhere on the listing appears in a copy speed field, reading 40 ppm, which means the print speed is not reliably stated here. Get it from HP’s own specification sheet before buying if throughput matters.
On running costs, the good news is the preinstalled consumables; the caution is what comes after. Four color toner cartridges plus four drums at enterprise capacities represent a significant replacement cost, and the listing does not state the cartridge part numbers or their page yields. Look those up for this model and work out cost per page before comparing against alternatives. A machine that is cheap to buy and expensive to feed is the standard trap in this category. Our toner cartridges category gives a sense of what equivalent consumables cost across brands.
Finally, the listing dates to July 2019. Check current firmware support, driver availability for your operating systems, and consumable availability before buying, since an enterprise printer is a long term commitment and all three matter over its life.
Who Should Buy It, and Who Should Not
Buy the M751dn if your organization prints color at volume, needs media larger than legal size, and values onsite warranty service on a machine too heavy to ship. The preinstalled full capacity toner and drums, the three tray configuration and the enterprise security posture all point at a device meant to run in a business for years rather than to sit on a desk.
Do not buy it if you need scanning, copying or fax, in which case an all-in-one such as the Brother MFC-L8900CDW or the HP LaserJet Pro M477fnw is the right shape. Do not buy it for a home office, where the size, weight, power draw and consumable costs are all far beyond what is sensible; a smaller machine such as the HP LaserJet Pro M426fdw or the Xerox C410 covers that ground. Our laser printers category covers the range from desktop to workgroup.
