Zebra ZD421d Desktop Label Printer (ZD4A043-D0EM00EZ)

The Zebra ZD421d is a 4-inch advanced desktop label printer for shipping, product, asset, pharmacy and healthcare labels – the successor to Zebra's popular GK and ZD420 printers. As a direct thermal model it needs no ribbon – ideal for shipping labels, receipts and short-life labels. It prints sharp 300 dpi labels up to 108 mm wide at up to 102 mm/s, supports both ZPL and EPL and is managed with Zebra Print DNA and Link-OS. This version, ZD4A043-D0EM00EZ, connects via USB and USB Host, with Bluetooth Low Energy for quick setup from the Zebra Printer Setup app – Ethernet, serial or Wi-Fi can be added later with field-installable modules; the power supply, EU and UK power cords and a USB cable are included, so it is ready to print as soon as you add labels.

Key Features

• Direct thermal – no ribbon needed – the simplest way to print shipping labels, receipts, visitor badges and food labels: just load a roll of thermal labels and print.
• Easy to operate – five status icons and a three-button interface show at a glance what the printer needs; colour-coded touch points and the OpenACCESS clamshell design make media changes quick.
• Handles virtually any media – roll-fed or fanfold labels, tags and continuous receipt paper from 15 mm to 108 mm wide, with a movable black-mark sensor and a multi-position gap sensor.
• USB today, network tomorrow – USB and USB Host as standard; the free modular connectivity slot takes a field-installable Ethernet or serial module, and a Wi-Fi + Bluetooth module can be added on site.
• Fits into your existing fleet – supports ZPL II and EPL 2, emulates other printer languages with Print DNA Virtual Devices and runs your existing GK-series label formats unchanged.
• Secure and remotely manageable – Print DNA with PrintSecure and Printer Profile Manager Enterprise; 512 MB flash, 256 MB SDRAM, real-time clock and ENERGY STAR certification.
• Upgrade on site – field-installable cutter or label dispenser, connectivity modules, an attached battery base for cart-based printing and the ZKDU keyboard display for stand-alone use.

Ideal Applications

• Transport and logistics – shipping, receiving and packing labels
• Retail – shelf labels, price markdowns, return tags and food information labels
• Healthcare and pharmacy – prescription, lab and specimen, blood bag and patient record labels
• Light manufacturing – product, agency, work-in-process and inventory labels
