Direct Thermal Printing – No Ribbon Required
The Zebra ZD421D uses direct thermal printing technology. Heat from the printhead creates the image directly on compatible heat-sensitive thermal labels, eliminating the need for ink cartridges, toner cartridges or thermal-transfer ribbons.
This makes the ZD421D particularly suitable for applications where labels are required for short to medium-term use, including shipping, logistics, inventory, retail and warehouse identification.
Fast 203dpi Label Printing
This configuration features a 203dpi (8 dots/mm) printhead and can print at speeds of up to 152mm per second / 6 inches per second.
The maximum printable width is approximately 104mm (4.09"), making it suitable for common 4-inch shipping and barcode label formats.
USB, USB Host & Ethernet Connectivity
The ZD4A042-D0PE00EZ configuration provides flexible wired connectivity for desktop and network printing:
- USB 2.0 – direct connection to a PC or compatible host
- USB Host – supports compatible USB peripherals and devices
- 10/100 Ethernet – built-in network connectivity for shared business printing
- Bluetooth Low Energy 5 – supports Zebra printer setup via compatible mobile devices
This specific ZD4A042-D0PE00EZ configuration includes Ethernet and Bluetooth Low Energy 5 but does not include Wi-Fi. Zebra states that the standard BLE connection is intended for use with the Zebra printer setup mobile application.
Ideal for Shipping & Barcode Labels
The Zebra ZD421D is well suited to a wide variety of commercial label-printing applications, including:
- Shipping and courier labels
- Warehouse and dispatch labels
- Barcode labels
- Inventory and stock identification
- Asset tracking labels
- Retail price and shelf labels
- Product identification
- Order fulfilment labels
- Receiving and logistics labels
Flexible Direct Thermal Media Support
The ZD421D supports direct thermal media up to approximately 108mm wide, with a maximum media roll outside diameter of approximately 127mm (5").
Its compact 4-inch desktop format makes it an excellent choice for businesses requiring professional label printing without the footprint of a larger industrial label printer.
ZPL & EPL Support
The Zebra ZD421 supports widely used Zebra printer languages including ZPL / ZPL II and EPL, helping businesses integrate the printer with existing Zebra-based label systems, warehouse software and compatible business applications.
This is particularly useful when replacing an older Zebra desktop printer while retaining existing label templates and workflows.
Easy Media Loading
Zebra's OpenACCESS™ clamshell design provides easy access to the media compartment, helping users quickly replace label rolls and minimise downtime.
The ZD421 also features a straightforward interface with five status icons and three control buttons, providing clear printer status information during everyday operation.
Zebra Print DNA
The ZD421 platform supports Zebra's Print DNA software ecosystem, providing tools and utilities designed to simplify printer configuration, deployment, management and security.
ZebraDesigner Essentials is also available for creating and printing basic barcode and label designs.
Compact Desktop Design
Despite supporting standard 4-inch label formats, the ZD421D maintains a compact desktop footprint:
- Length: Approx. 220.8mm
- Width: Approx. 177.5mm
- Height: Approx. 150.7mm
