Expanding Zebra’s RFID Desktop Capabilities
Print and Encode 4-Inch Labels and Tags
Building on the ZD500R, the ZD621R uses an innovative architecture that Zebra rates as nearly 32% more powerful. It can perform more operations simultaneously, apply best-practice security and evolve with emerging technology while printing and encoding media up to the 4-inch class.
The printer supports UHF EPC Gen 2 V2.1, ISO/IEC 18000-63 and RAIN RFID tags. Industry-standard multi-vendor chip-based serialization and RFID ZPL commands help it fit established enterprise RFID environments.
Zebra RFID: More Transformation, No Complication
Flexibility for a Broad Range of Uses and Applications
Zebra's integrated RE40 reader/encoder supports RFID labels, tags and wristbands across multiple industries. Adaptive Encoding Technology simplifies calibration and removes the need for complex inlay-placement guidelines, giving users more freedom in media selection.
The ZD621R can print and encode tags with a minimum pitch of 0.6 inch/16 mm. RFID job-monitoring tools track performance, and a timestamped RFID log records RFID data for complete operational traceability.
RFID Backed by the Broadest, Field-Proven Portfolio
Zebra applies decades of RFID expertise, design work and software development across readers, printers, tags and enterprise systems. The ZD621R is globally certified for RFID in more than 70 countries, supporting organizations that standardize deployments across regions.
That common platform is designed to address real-world interoperability issues that can arise in multi-vendor environments. The result is a desktop printer/encoder positioned for consistent tracking, deeper visibility and enterprise insight.
Expect the Best
Premier Printing Performance
The thermal transfer and direct thermal ZD621R combines RFID encoding with premium desktop print quality. Standard 203 dpi printing reaches 8 ips, while optional 300 dpi reaches 6 ips for small text, dense barcodes and compact label designs.
Operate with Ease
Intuitive User Interface
The 4.3-inch full-color touch display uses step-by-step setup wizards, troubleshooting animations, media-loading guidance and calibration assistance. The screen changes color to show status at a glance, while color-coded touch points guide users through quick media changes.
Zebra tests its touch displays for toughness and reliable operation across temperature, humidity, dust and other environmental challenges. Guided operation reduces training requirements and makes common adjustments available at the printer.
Backwards Compatible with Virtually Any Existing Thermal Printer
ZPL and EPL support lets organizations continue using existing formats and applications, while Zebra DNA Printer Emulations can interpret languages associated with other printer brands. This reduces the disruption of replacing an older thermal printer.
Connect Your Way with Comprehensive Communication
Ethernet, USB 2.0, USB host and serial are standard on the ZD621R. Optional dual radios pair 802.11ac Wi-Fi with Bluetooth 4.1 or 802.11ax Wi-Fi with Bluetooth 5.3, and Bluetooth Low Energy connects the Zebra printer setup mobile app on supported mobile platforms.
Engineered for Outstanding Print Quality
Like Zebra industrial printers, the ZD621R includes a media dancer to maintain quality at different print speeds. OpenACCESS media loading, a dual-wall frame and movable reflective plus multi-position transmissive sensors support reliable everyday operation.
Zebra DNA for Printers
Print Securely and Confidently, Without Hassles
Zebra DNA software, powered by Link-OS, helps the ZD621R start quickly, print consistently and remain adaptable as requirements change.
Update, Troubleshoot and Monitor, All from a Single Location
Printer Profile Manager Enterprise can manage Zebra DNA printers around the world remotely from a single location.
Unparalleled, Peace-of-Mind Printer Security
PrintSecure helps administrators configure secure connections, identify vulnerabilities and block unauthorized access. These tools protect the printer endpoint while giving IT centralized visibility and control.
Explore Managed Print Services (MPS) with Assurance
Zebra’s Thermal Printers with Zebra DNA Make MPS Easy
The ZD621R combines durable hardware with management, analytics and security functions suited to managed print services. A provider can remotely manage printers, track and automate supplies activity and maintain security while reducing an organization's operating costs and IT workload.
Remote visibility complements the printer's guided local interface rather than replacing it. Operators can resolve common tasks at the device while administrators address fleet-wide settings and health centrally.
Get the Features you Need, When you Need Them
Turn Your ZD621R Into a Portable Printer
An optional high-capacity battery supports a full shift at maximum print speed and enables printing from a mobile cart. A carrying case is available for the ZD621R when a cutter or peeler is not attached.
Factory- or field-installable dispenser/peeler and cutter options adapt output handling, and wireless options can be added as needs change. These choices help extend the useful life of the printer instead of locking a deployment into its initial configuration.
