Performance and Print Quality
The M455dn excels in its primary task: printing. It boasts fast speeds, generally around 27-29 pages per minute for both black and color documents, ensuring minimal waiting time even for large print jobs. Its First Page Out Time is also quick, taking around 9.5 seconds for black and 11.0 seconds for color prints, which is crucial for maximizing productivity in a busy office setting.
For a color laser printer, the output quality is a definite strength. With a resolution of $600 \times 600 \text{ dpi}$ enhanced by HP ImageREt 3600 technology, the M455dn delivers crisp, professional-grade text and graphics. It handles color documents, presentations, and internal marketing materials with notable vibrancy and clarity, making it a reliable choice for businesses that need impressive color output without relying on inkjet photo printers.
Enterprise-Grade Security and Management
One of the most significant advantages of choosing an Enterprise model like the M455dn is the integration of HP's cutting-edge security features. In today's threat landscape, where printers are often overlooked network endpoints, HP has built-in layered protection:
Self-Healing BIOS: The operating code is automatically checked during startup and repairs itself if compromised.
Real-Time Intrusion Detection: The printer continually monitors memory activity to detect and thwart attacks as they happen.
Firmware Validation: Checks that the firmware is authentic and digitally signed by HP.
PIN/Pull Printing: Helps ensure that confidential information remains secure by requiring a PIN code or card reader (optional accessory) to retrieve print jobs.
For IT management, the printer uses HP FutureSmart firmware for future-proofing and features centralized control via HP Web Jetadmin, allowing for efficient, fleet-wide management and security configuration.
Design, Handling, and Connectivity
The M455dn features a relatively compact design for an enterprise-class laser printer (approximately $414 \times 472 \times 304 \text{ mm}$ minimum dimensions), making it suitable for placement in workgroups without demanding excessive space . It is a single-function device, which means it does not include scanning or copying, a trade-off that keeps its size down but may require a separate multifunction peripheral (MFP) for all-in-one needs.
Paper handling is solid, with a standard input capacity of 300 sheets (50-sheet multipurpose tray and a 250-sheet main tray). The recommended monthly page volume of 900 to 4,800 pages, with a max duty cycle of 55,000 pages, confirms its role as a sturdy office workhorse.
Connectivity is geared towards a professional network environment, featuring Gigabit Ethernet and USB. Notably, Wi-Fi and Bluetooth are not standard but can be added via an optional accessory (like the HP Jetdirect 3100w). The automatic duplex printing (two-sided) is enabled by default, contributing to paper and cost savings right out of the box.
Conclusion: A Solid, Secure Color Workhorse
The HP Color LaserJet Enterprise M455dn (3PZ95A) is an excellent choice for a business or enterprise workgroup that places a high value on print quality, speed, and uncompromising security. It is a reliable, dedicated color laser printer built for consistent, heavy-duty usage. While the lack of built-in wireless connectivity might be a minor drawback for some modern offices, its strong network performance, automatic duplexing, and comprehensive security suite make it a highly competitive and dependable asset for any organization focused on professional, high-volume color document output.
