Zebra ZT421R

Versatile to Meet Your Evolving Needs

Configure Your Way With Multiple Connectivity Options

Ethernet, RS-232 serial, USB 2.0, dual USB Host and Bluetooth 4.1 are standard. Optional dual-band wireless is available with Wi-Fi 6/6E through 802.11ax and Bluetooth 5.3, or with Wi-Fi 5 through 802.11ac and Bluetooth 4.2.

Built to Handle a Wide Range of Applications Including High-Resolution

The ZT421 RFID handles continuous, die-cut, notched and black-mark media across a broad width range and can print and encode tags with a minimum 0.6-inch pitch. Its 6.6-inch maximum print width supports larger compliance, pallet, shipping and asset labels while 203- and 300-dpi configurations provide a choice between throughput and finer output.

Versatile to Meet Your Evolving Needs

Dual USB Host Ports For Added Flexibility

Two USB Host ports can connect storage, scanners, keyboards and other peripherals at the same time. Operators can replicate firmware, files and configurations, transfer formats or simplify data entry without repeatedly swapping devices.

Designed to Evolve With Your Needs

Field-installable media-handling and RFID options allow the ZT421 to change after deployment. Two open communications slots, robust processing and memory support new interfaces, firmware updates and additional Zebra DNA tools over the printer's service life.

Effortless to Integrate and Operate

Large Color Touch Display Makes Operation a Snap

The 4.3-inch full-color touch display uses an intuitive icon-based menu for printer and RFID configuration. Operators can create frequently used shortcuts and see color-coded alerts from a distance when the printer is paused or in an error state.

Print and Encode With Ease

Adaptive Encoding Technology simplifies RFID calibration and removes complex inlay-placement guidelines. Zebra's globally certified RFID technology supports deployments on six continents, while variable inlay placement and a Global RFID radio help multinational supply chains standardize processes.

Effortless to Integrate and Operate

Easy Media and Ribbon Loading

The side-loading supplies path, color-coded guides and illuminated media and ribbon paths make loading faster and easier to understand. Even in poorly lit environments, operators can see how supplies should be threaded and reduce loading errors.

Space-Saving Design For an Easier Fit

A bi-fold metal media door reduces the overhead clearance needed for access. The ZT421 remains a substantial industrial printer with an approximately 19.5-by-13.25-inch closed footprint, but the door design helps it fit where a full-height swing-up cover would not.

Effortless to Integrate and Operate

Direct Connection to Your Industrial Ethernet Network

The optional Network Connect capability links the ZT421 directly to an Industrial Ethernet network without separate equipment. Zebra positions this as a way to remove vulnerability points and reduce setup, management and troubleshooting labor.

Pair Devices and Access Information at a Touch

Print Touch uses NFC to pair compatible devices with a tap. Dynamic QR codes provide immediate access to printer-specific help, including Zebra how-to videos and product support resources.

Easy to Manage

Zebra DNA for Printers—Transforming Printers From the Inside

Zebra DNA for Printers combines productivity, management, development and visibility tools on the Link-OS operating system. The software environment improves integration and remote manageability while giving teams tools to deploy and configure printers consistently.

Easily Manage All Your Printers—All From a Single Location

Printer Profile Manager Enterprise can discover Link-OS printers and manage one device, selected groups or a global fleet through a browser. Administrators can maintain, secure and troubleshoot without manually visiting every printer, supported by complimentary deployment utilities for initial setup.

Easy to Manage

Seamless Integration With Your Device Management System

Zebra DNA MDM Connectors integrate networked ZT400 printers into supported device-management platforms. Zebra specifically identifies AirWatch and SOTI MobiControl, allowing printers and mobile devices to appear in a more unified administrative workflow.

Performance You Can Count On

The ZT421 prints at up to 12 inches per second across a 6.6-inch print width, helping teams produce large labels without moving to a separate wide-format platform. A 300-dpi option supports smaller text, denser barcodes and more detailed graphics when a workflow needs additional definition.

Rugged Durability For Demanding Applications

A metal frame and metal media enclosure support years of industrial use. A long-life printhead coating protects direct-thermal operation, while printhead-element-out detection helps maintain quality and identify maintenance needs before output deteriorates.

Performance You Can Count On

Consistently Exceptional Zebra Certified Supplies

Zebra designs, produces and pretests thermal labels, tags and ribbons to support consistent printer performance and printhead life. RFID media should also be qualified for encoding performance, inlay placement and the surface on which the tag will be used.

Maximize Uptime, Business Operations and Printer Visibility With Services

Zebra OneCare adds direct technical support and repair options that can include accidental-damage coverage and defined turnaround times. Zebra Support and Visibility Services add operational insight intended to improve availability and printer utilization.

RFID

The integrated reader/encoder supports UHF EPC Gen 2 V2.1, ISO/IEC 18000-63 and RAIN RFID tags. It also supports multi-vendor chip-based serialization, job-monitoring tools and block permalocking of user memory compatible with ATA Spec 2000.

The RFID system can be upgraded in the field, allowing the printer to evolve from ordinary label output to RFID encoding when requirements change. Adaptive encoding and variable inlay placement preserve media flexibility instead of forcing one rigid inlay position.

RFID job-monitoring tools give operators visibility into encoding performance instead of treating RFID output as a blind print step. Global radio compliance and standards-based serialization further support consistent deployment across sites and suppliers.

The ZT400 Series RFID is ideal in:

Manufacturing

Manufacturing uses include item and asset tagging, work-in-process, product ID or serial numbers, packaging and receiving.

Transportation and Logistics

Transportation and logistics workflows include picking and packing, shipping and receiving, cross-docking, compliance labeling and pallet or asset tagging.

Retail

Retail applications include back-of-store work, item-level and security tagging, and distribution-center operations.

Healthcare

Healthcare workflows include laboratory, specimen and pharmacy labeling plus asset management and tagging.
