HP LaserJet Pro 4001dn Review — Fast Monochrome Laser
In-depth review of the HP LaserJet Pro 4001dn: 42ppm monochrome laser, 1200dpi, duplex, Ethernet, enterprise security, ideal for small teams.
Introduction
The HP LaserJet Pro 4001dn is a business-focused monochrome laser printer built to deliver fast, reliable output for small teams. With up to 42 pages per minute, automatic duplexing, and a compact footprint, it tackles one of the most common office pain points: slow, inconsistent document throughput. Whether you need crisp reports, multi-page contracts, or high-volume daily prints, this model is optimized to keep workflows moving and reduce bottlenecks.
Beyond speed, the 4001dn addresses security and manageability — two priorities for modern offices. HP Wolf Pro Security, centralized administration tools, and support for HP’s Instant Ink for lasers solve real-world problems: protecting sensitive data, simplifying IT oversight, and making supplies predictable. For organizations that prioritize dependable black-and-white printing, the LaserJet Pro 4001dn positions itself as a productivity-first machine that reduces downtime and ongoing operational friction.
Overview
The LaserJet Pro 4001dn pairs a clean, compact design with rugged internal components that emphasize uptime and consistent output. At roughly 14.1 x 15 x 8.5 inches and under 19 pounds, it fits comfortably on a small office desk or a shared print station. The exterior is straightforward and professional — tactile controls and status LEDs make quick checks simple, while two paper trays and a 350-sheet maximum input capacity reduce the frequency of reloads.
At its core is laser printing technology tuned for monochrome document production: high-definition 1200 x 1200 dpi rendering for text and line art, a first-page-out time near six seconds, and a 42 ppm top speed. Connectivity is focused on wired reliability — Ethernet and USB interfaces provide stable, high-bandwidth links for shared environments and direct-attached workstations. The 4001dn is ideal for small workgroups (up to ~10 users) or branch offices that need efficient, scalable, and secure printing without the complexity or variability of wireless setups.
Features
Blazing Fast 42 ppm Output: Delivers up to 42 black-and-white pages per minute single-sided with a 6.1-second first page out time. This high throughput shortens job queues, speeds multi-page workflows, and reduces wait times for shared office printers.
Automatic Duplex and Robust Paper Handling: Built-in auto two-sided printing and a max input capacity of 350 sheets across two trays mean fewer interruptions for paper loading and lower paper costs for double-sided documents and reports.
Enterprise-Grade Security — HP Wolf Pro: Preconfigured security features, PIN/pull release for secure jobs, and centralized policy controls help protect documents and device settings from unauthorized access and minimize exposure of sensitive information.
Wired Connectivity for Stable Networks: Ethernet and USB ports deliver rock-solid connections for multi-user environments and IT-managed fleets. HP Web Jetadmin and Smart Admin provide centralized setup, monitoring, and policy enforcement to simplify administration.
High-Resolution Monochrome Printing: 1200 x 1200 dpi resolution produces crisp, professional text and sharp line art suitable for invoices, contracts, and business collateral where legibility and presentation matter.
Benefits
Faster Office Throughput
High page-per-minute performance translates directly into shorter wait times, faster document circulation, and greater daily capacity — particularly valuable for small teams with heavy printing demands.
Lower Operational Interruptions
Auto-duplexing and larger tray capacity minimize user intervention. With fewer paper refills and automatic two-sided printing, staff can focus on work instead of managing the printer.
Stronger Document Security
HP Wolf Pro and PIN/pull options provide peace of mind for offices handling confidential invoices, HR materials, or legal documents. Centralized security settings reduce configuration errors and exposure from misconfigured devices.
Predictable Supplies and Reduced Waste
Integration with Instant Ink for lasers streamlines toner replenishment and recycling, preventing out-of-toner surprises and consolidating supply billing for multiple locations.
Reliable Networked Printing for IT Teams
Ethernet-only connectivity reduces wireless troubleshooting while Web Jetadmin and Smart Admin enable IT to deploy, monitor, and configure several units from a single dashboard, saving administrative time.
Usages
Perfect for Small Teams and Branch Offices
Designed to handle the daily output of up to around 10 users, the 4001dn supports invoices, multi-page reports, and forms with high speed and minimal management overhead.
Ideal for High-Volume Document Workflows
Law offices, accounting departments, and logistics teams that require repeatable, fast black-and-white printing will benefit from the 42 ppm speed and automatic duplex features.
Secure Printing for Regulated Environments
Healthcare, HR, and finance departments will appreciate the secure release and policy controls that reduce accidental exposure of protected documents.
Centralized Fleet Management Use Case
IT-managed environments that rely on Web Jetadmin can deploy consistent settings, monitor consumables, and implement security policies across multiple LaserJet Pro 4001 units with minimal effort.

FAQs
Does the HP LaserJet Pro 4001dn support Wi‑Fi?
No. This model supports Ethernet and USB only. For wireless printing, consider the LaserJet Pro 4001dw variant or another wireless-enabled model.
Can I use third-party toner cartridges?
The printer is designed to work with Original HP toner cartridges that include HP chip technology. The device may block non-HP chips or cartridges, and firmware updates can enforce this behavior.
Is this printer good for photo printing?
This is a monochrome office laser intended for text and line art. It is not suitable for photo printing or color graphics — choose a color laser or dedicated photo printer for that use.
What management tools are available for IT administrators?
HP Web Jetadmin and Smart Admin provide centralized setup, configuration validation, and monitoring capabilities, simplifying rollout and maintenance across multiple devices.
Does it support mobile printing like AirPrint?
Yes. Although it lacks Wi‑Fi, the printer supports mobile and platform printing over a network (Ethernet) and is compatible with AirPrint, Android printing, and Chromebook printing when connected to the same network.
