New LaserJet Pro 4000/4100 Series Launch

The HP LaserJet Pro 4000 and 4100 Series target small and growing businesses seeking reliable monochrome printing in compact designs. These printers deliver professional-quality output while prioritizing security and cost efficiency.

Quantum-resistant security stands out as the headline feature. No other in-class SMB printer offers this preinstalled encryption, authentication, malware protection, and post-quantum digital signature with BIOS firmware integrity as of early 2026. This protects firmware from advanced attacks, crucial as quantum computers evolve.

TerraJet Toner technology reduces print costs by up to 25% compared to prior high-yield cartridges. Businesses benefit from lower ongoing expenses, making high-volume printing more accessible for teams with tight budgets.

A three-year warranty backs the series upon registration within 60 days of purchase. This coverage applies subject to HP's terms, providing long-term reliability for resource-limited organizations.

Easy setup and management suit non-IT users. The compact form factor fits small offices navigating hybrid work, where space and simplicity matter.

Quantum-Resistant Security Explained

Quantum-resistant security addresses vulnerabilities in current encryption from quantum computers. Traditional methods like BitLocker face bypass risks, but these printers use post-quantum cryptography to secure BIOS and firmware.

This first-of-its-kind feature for SMBs prevents physical and remote attacks. HP's internal analysis confirms no competitors match this in business printers as of March 2026.

Sensitive documents stay protected during printing and storage. For industries like legal, healthcare, and finance, this reduces breach risks in hybrid environments.

Preinstalled protections include encryption, authentication, and malware defense. Automatic self-healing recovery ensures uptime even after threats.

Businesses gain peace of mind without add-ons. This aligns with HP's security leadership, including recent HP TPM Guard for laptops.

AI-Powered Workflow Integration

These printers accelerate document digitization with AI features. Scan AI Enhanced and Editable OCR turn paper into editable digital files quickly.

Organizations reduce manual processing by streamlining scans. This supports hybrid teams bridging physical and digital documents.

Integration with HP's Workforce Experience Platform expands automation. Connected capabilities link printing to broader office ecosystems.

HP Build Workspace connects to large-format printers and workstations. This creates real-time alignment from design to execution, vital for construction and engineering.

Cost savings pair with efficiency gains. Lower toner costs and faster workflows lower total ownership expenses.

Cost Efficiency and Reliability Features

TerraJet Toner delivers up to 25% lower cost per page versus previous models. North American comparisons use HP 161X versus 148X cartridges.

High-speed printing and scanning handle demanding volumes. Compact designs save desk space without sacrificing performance.

Three-year warranty covers hardware issues under standard terms. Registration ensures extended protection for critical tools.

Serviceability emphasizes durability. Parts replace quickly, minimizing downtime for busy teams.

Hybrid work demands reliable tools. These printers support remote and office printing securely.

Enterprise Counterpart: LaserJet 5000/6000 Series

The LaserJet Enterprise 5000/6000 Series complements for larger businesses. High-speed operations suit fast-paced environments.

HP FutureSmart firmware enables over-the-air updates. Devices stay current against evolving threats.

AI reduces document processing time by up to 50%. Editable OCR and enhanced scans boost productivity.

90% of parts replace in under eight minutes. This streamlines maintenance for IT teams.

Quantum-resistant features extend here too. Large firms gain scalable security.
