✅ Performance and Print Quality: Speed Meets Consistency
The M555dn is built for speed. With a consistent print rate of up to 38 pages per minute (ppm) for both black and color documents, this printer easily handles large print jobs and keeps office workflow moving. The standard automatic duplex (two-sided) printing feature is a major productivity booster, matching the single-sided speed at up to 38 images per minute (ipm), and simultaneously helping to reduce paper consumption.
The output quality is truly professional. Utilizing HP ImageREt 3600 technology, the printer delivers sharp text and remarkably vibrant color graphics. For businesses that rely on producing high-impact reports, presentations, or marketing materials in-house, the M555dn provides results that are more than suitable for outgoing documents. The quick First Page Out time (under 8 seconds for color) means minimal waiting, even when retrieving single documents.
🛡️ Enterprise-Grade Security: HP's Strongest Defense
One of the most compelling reasons to choose an Enterprise-series printer is the robust security suite, and the M555dn does not disappoint. In a renewed capacity, it retains crucial features that protect sensitive corporate data.
Self-Healing BIOS: The printer automatically checks its operating code (BIOS) during startup and repairs itself if compromised, a vital defense against firmware attacks.
Run-time Intrusion Detection: It constantly monitors memory activity to detect and stop real-time attacks.
Whitelisting: Firmware is checked for authenticity (digitally signed by HP) to ensure only genuine, known-good code is running.
For organizations handling confidential information, these advanced security layers are essential and provide peace of mind that a standard office printer cannot match.
📈 Efficiency and Paper Handling: Built for High Volume
With a substantial Recommended Monthly Page Volume of 2,000 to 10,000 pages and a maximum duty cycle of 80,000 pages, the M555dn is clearly designed for busy workgroups. The standard paper capacity of 650 sheets is excellent, and it can be significantly expanded with optional trays, allowing the printer to run for extended periods without manual paper refills.
The use of high-yield HP 212X toner cartridges, while initially costly, results in a lower cost per page (CPP) and reduces the frequency of cartridge replacement. This translates to less downtime and a lower total cost of ownership (TCO) over the printer's lifespan—a key consideration for a Renewed unit where long-term operational costs are critical.
💻 Usability and Connectivity
The printer features an intuitive 4.3-inch color touchscreen display that can be rotated for ease of use. This panel allows users to manage print jobs, adjust settings, and access the printer's security and maintenance functions easily.
Standard connectivity is wired, offering Gigabit LAN (Ethernet) and USB 2.0. While the dn suffix indicates Duplex and Network readiness, wireless capability is optional, requiring an additional hardware accessory. The printer is compatible with various mobile and cloud printing solutions like HP ePrint, Apple AirPrint, and Mopria Certified, making it accessible from a wide range of devices on the network.
💡 The Renewed Advantage: Value and Sustainability
Choosing a renewed (refurbished) HP Color LaserJet Enterprise M555dn (7ZU78A) is a smart decision for budget-conscious businesses that still require enterprise-level performance.
Cost Savings: Renewed units typically offer a substantial discount compared to brand-new models.
Sustainability: Extending the life of a robust piece of office equipment contributes to a circular economy, reducing electronic waste.
Quality Assurance: Reputable renewed products are rigorously tested and certified to ensure they meet original performance standards, often coming with a limited warranty.
Summary: Who is the Renewed M555dn For?
The Renewed HP Color LaserJet Enterprise M555dn is an outstanding choice for medium to large workgroups in corporate environments, financial institutions, or legal offices. It's ideal for those who:
Need fast, high-volume color and monochrome printing.
Demand top-tier security features to protect sensitive data.
Want professional-quality output for client-facing documents.
Are looking for an excellent value proposition by opting for a certified renewed enterprise machine.
While its size and weight might make it difficult to move, and the OEM toner is pricey, these are minor trade-offs for a device that delivers such a high level of performance, reliability, and security. The renewed M555dn is a testament that a previous-generation enterprise printer can still be a powerful, economical workhorse today.
