HP Color LaserJet Enterprise M750n: 850-sheet wide-format color with manual duplex review

Wide-format color with three inputs and an attended second pass

The HP Color LaserJet Enterprise M750n fits a commercial computer queue needing color A3 or 11×17-inch documents and a substantial ordinary-paper reserve. It includes Ethernet, rear computer USB and 850 standard sheets. The n configuration's decisive limitation is manual duplex: automatic two-sided promotional wording elsewhere on the family page does not override its exact technical field.

HP identifies D3L08A#BGJ and explicitly marks it discontinued. This earlier-model review concerns the documented US commercial Class A, 110–127-V edition at 50/60 Hz. Check the actual plate, condition, accessories and compatible host driver. A separate high-voltage unit is not dual voltage or an interchangeable electrical edition.

Use the 850-sheet reserve for the actual loaded size

The standard front 100, Tray 2's 250 and Tray 3's 500 total 850 ordinary sheets. The original counts use 20-lb/75-g/m² stock. Actual tables positively include Letter, Legal, A4, A3 and 11×17 in all three inputs. Full capacity for one size assumes all three contain it; keeping forms or several sizes loaded divides that reserve.

Open the front extension, keep the stack under the tabs and fill indicators, and adjust guides so they touch without bending paper. In a drawer, squeeze the guide latches, set width and length, load below its line and confirm the panel's size and type. Choose Modify if those settings differ from the real stock, then make the computer job agree.

Tray 1's Any Size/Any Type behavior deserves attention: when the job does not specify a tray, the guide warns it can print from the front even when its contents do not match the requested settings. Explicit source, size and type are useful for a carefully prepared color job. Expanded 2,350-sheet capacity needs optional feeders.

Reload printed sides face up for manual duplex

In the compatible Windows HP driver, open Finishing and select Print on both sides manually. After the first pass, retrieve the stack and put it in Tray 1 with the printed side facing up, then follow the panel prompt. The original Mac HP-driver procedure separately removes blank front paper and also returns printed sides up.

This direction is specific to the M750 original and differs from some monochrome LaserJet guides. A person must still collect and reload the stack. If unattended second sides are essential, compare the actual M750dn configuration instead of relying on the family name or a broad automatic-duplex paragraph.

For one-sided portrait preprinted paper, the front orientation table gives face down with the top toward the back; lower drawers use face up/top at the back. Landscape and Alternative Letterhead Mode have their own directions. Follow the actual orientation and driver setting rather than using one remembered rule for every form.

Distinguish plain, coated and envelope stock

The exact US fields and detailed original type table limit lower ordinary paper to 120 g/m², with approved coated stock up to 160. Front input reaches 220, with reduced capacity for thicker material. A separate generic guide table claims higher lower-tray limits; this review keeps the more specific conservative type limits.

Use laser-approved coated media, not inkjet photo stock. Up to ten suitable envelopes no heavier than 90 g/m² use Tray 1 face down, short edge entering, with the top toward the back of the printer. Select the actual size and type. Envelope printing is one-sided and is not a reason to borrow another generation's face-up instruction.

Release a computer PIN job and keep mobile printing separate

The exact US configuration lists 1 GB RAM and included 8-GB solid-state storage. A compatible driver offers Personal Job with PIN protection; the original Mac procedure uses four digits. At the panel choose Retrieve from Device Memory, the folder and job, enter the code and release copies.

Names may gain a number or replace an earlier file, and space pressure may remove older jobs. Keep the source elsewhere. The actual M750 prose does not establish an automatic post-print or power-loss deletion rule, and this n does not include the xh's encrypted hard disk.

Exact US specifications also list AirPrint and Mopria. A separate local mobile arrangement uses printer Ethernet and a compatible client reaching the same network through its wireless router. Mobile paper size, input count, duplex and PIN remain unconfirmed. The original expressly excludes USB AirPrint; wireless hardware requires the optional Jetdirect accessory.

The front flash-file USB host is distinct from rear computer USB, and its enablement should follow the exact online instructions referenced by the guide. A color display, four toner cartridges and stored jobs do not add scanning, copying or fax to this print-only machine.

Keep color settings and consumables concrete

The driver provides Automatic/HP EasyColor and grayscale controls. Grayscale reduces color-cartridge use without proving every gray uses black alone; the separate Neutral Grays setting distinguishes Black Only from four-color neutral gradients. No measured color-accuracy or photo-quality result is claimed.

The exact supply table identifies CE270A black and CE271A/CE272A/CE273A cyan/yellow/magenta. Their declared replacement yields are approximately 13,500 black and 15,000 CMY pages under the exact HP 650A continuous-printing ISO/IEC 19798 wording. The box lists four cartridges without a separately established supplied yield here.

HP recommends 2,500–13,000 monthly pages, distinct from 120,000 maximum duty. Declared one-sided Letter speed is up to 30 ppm in black and color. The US body is 21.4×23×18 inches and 115.3 lb; allow its approximately 33×38.5-inch opened footprint plus service room before choosing the actual manual-duplex arrangement.
