Zebra ZD421T Healthcare 300 dpi Thermal Transfer Label Printer USB Ethernet [ZD4AH43-30PE00EZ]

The Zebra ZD421T Healthcare [ZD4AH43-30PE00EZ] is a genuine Zebra 300 dpi thermal transfer label printer with USB and Ethernet. Its healthcare housing uses disinfectant ready plastics and a sealed button interface, while the higher resolution suits detailed label layouts.

This is the thermal transfer ribbon roll version, accepting 74 m and 300 m ribbons. BLE 5 is provided for Zebra's printer setup app only, not ordinary Bluetooth Classic printing.

Value for Your Business

Choose this configuration when detailed labels and the healthcare housing are priorities. Thermal transfer allows a choice of compatible ribbon and label materials, but resistance to chemicals, handling or storage conditions depends on the supplies selected. The housing does not replace workplace cleaning procedures or application validation.

Key Features

• Healthcare design: White housing, disinfectant ready plastics and sealed buttons. Use Zebra's approved cleaning procedures.
• Wired connections: USB and Ethernet are included. WiFi and Bluetooth Classic printing are not included in this part number.
• Media flexibility: Thermal transfer printing with matching ribbon and media, or direct thermal mode for suitable labels.
• Daily operation: Five status icons, three buttons and movable media sensing assist printer use.
• Software integration: Zebra Link OS supports compatible label applications.

Compatibility and Media

Accepts media from 15 to 112 mm wide, including backing, with rolls up to 127 mm outside diameter. Standard media cores are 12.7 mm and 25.4 mm. Match ribbon width, core and formulation to your labels. Media width is not the same as printable width; confirm the usable label area and template before ordering supplies.

For laboratory, pharmacy or patient identification applications, validate the exact media, adhesive, expected durability and software integration. This is a ribbon roll model, not a ZD421C ribbon cartridge printer.
