HP LaserJet Pro MFP 4102fdw review: a fast mono laser all-in-one for busy small teams

Anyone searching for an HP LaserJet Pro MFP review in 2026 will find several model numbers. The current generation is the LaserJet Pro MFP 4100 series. In Germany and the rest of Europe the fully featured version is the 4102fdw, while the US equivalent is the 4101fdw. This review focuses on the 4102fdw, and most points apply to its US sibling too.

Our assessment is based on HP's datasheet and product page, independent reviews and test summaries, and owner reports. We look at speed, paper handling, scanning, running costs and HP's cartridge policy, which is the most important thing to understand before you buy.

Which HP LaserJet Pro MFP 4102 model should you buy?

HP sells several versions. The 4102fdw adds fax and wireless to the core print, copy and scan functions. The 4102dw keeps wireless printing but drops fax, and HP also lists a 4102fdn variant. Models ending in 'e' are sold through HP+, which requires an HP account, an internet connection and original HP toner in return for extra perks.

If you want freedom over supplies and do not need HP's subscription extras, the standard 4102fdw is the more flexible pick.

Design and paper handling

The 4102fdw is compact for a business all-in-one at about 42 by 39 by 32 cm and 12.6 kg. It has a 2.7-inch colour touchscreen, a front USB port for walk-up printing and scanning, and a 150-sheet output bin.

Paper handling is generous. A 100-sheet multipurpose tray sits above a 250-sheet main tray, giving 350 sheets as standard, and an optional 550-sheet tray lifts the maximum to 900. That means you can keep letterhead and plain paper loaded at the same time.

Print speed and quality

HP rates the 4102fdw at up to 40 pages per minute on A4 and 34 images per minute in duplex, with the first page arriving in as little as 6.3 seconds from ready. Automatic two-sided printing is the default, which saves paper. Home Office Research called the US 4101fdw the fastest printer in its guide.

Reviewers consistently describe the text as crisp and professional, which is what a mono laser is for. It cannot print colour, so charts and photos will come out in greyscale. HP recommends between 750 and 4,000 pages per month and lists a maximum duty cycle of 80,000.

Scanning, copying and fax

The 50-sheet automatic document feeder scans both sides in one pass, which makes digitising contracts or invoices quick. Optical resolution reaches 1200 dpi, and you can send scans to email with address lookup, network folders, USB sticks, SharePoint or cloud services such as Google Drive and Dropbox.

Copying runs at up to 38 copies per minute with ID copy and resize options, and the fax modem stores up to 400 pages in memory.

• Single-pass duplex scanning up to 46 images per minute in black and white
• Fax archive to email or network folder
• Scan to Microsoft SharePoint
• Shortcuts through the HP Smart app

Security and management

HP Wolf Pro Security arrives preconfigured, and PIN or pull printing holds jobs until the user is at the printer. Self-healing Wi-Fi detects problems and restores a safe state. IT teams can manage fleets through HP Web Jetadmin and HP Security Manager. The printer holds a Blue Angel label in Germany when used with original HP supplies.

Energy use and sustainability

HP lists power draw of about 510 watts while printing, 7.5 watts when ready and 0.9 watts in sleep. HP Auto-On/Auto-Off technology powers the printer down when it is idle and wakes it when a job arrives. HP also says its EcoSmart toner with JetIntelligence can save up to 20 percent energy, and the printer carries Energy Star certification.

Duplex printing is switched on by default, which halves paper use for most documents. The chassis contains post-consumer recycled plastic, and HP supplies can be returned through its Planet Partners recycling programme. For German buyers, the Blue Angel label is a useful sign of low emissions, though it only applies when original HP supplies are used.

Toner costs and HP's cartridge policy

The printer uses HP 149A toner rated for 2,900 pages and the high-yield 149X rated for 9,500 pages. The box includes a starter cartridge rated for 2,900 pages. Buying the 149X is the obvious way to keep the cost per page low in a busy office.

HP states clearly that the printer is intended to work only with cartridges that have a new or reused HP chip, and that firmware updates may block cartridges that previously worked. Refilled or remanufactured toner with a reused HP chip is allowed. If you rely on cheap third-party cartridges, this is a real drawback and a reason to consider Brother.
