The ZEBRA ZD421 is an advanced 4-inch desktop label printer, which is an upgraded and enhanced model based on Zebra's previous GK series and ZD420 series. It is characterized by flexible printing modes, reliable performance and convenient operation, and is widely used in healthcare, logistics, retail and other fields. Here is a detailed overview:
Core Printing Specifications
Printing Technology: It supports three modes including direct thermal, thermal transfer roll and thermal transfer cartridge, and can be selected according to different label durability requirements. Resolution & Speed: It has two resolution options of 203dpi and 300dpi. The maximum printing speed is 6ips (152mm/s) when the resolution is 203dpi, and 4ips (102mm/s) when it is 300dpi, which balances efficiency and printing clarity. Print Width: The maximum print width is 104mm (203dpi) and 108mm (300dpi) respectively, which is compatible with most 4-inch standard labels and meets the needs of common labeling scenarios.
Connection & Operation Experience
Diversified Connections: It comes with USB and USB host ports as standard. It also provides optional configurations such as Ethernet, serial port, Wi-Fi 6/Bluetooth 5.3 or Wi-Fi 5/Bluetooth 4.1. It supports NFC touch pairing and Bluetooth low energy connection, and can be quickly connected to devices such as Windows, Android and iOS. Intuitive Operation Interface: It is equipped with a three-button operation panel and five LED status indicators, which can intuitively display the working state of the printer. The color-coded contact points can guide the replacement of media, and the thermal transfer cartridge model supports one-way error-proof quick loading, which shortens the replacement time of the ribbon.
Physical Parameters & Mobility
Size and Weight: The size and weight vary slightly by model. The direct thermal model is 220.8mm × 177.5mm × 150.7mm and weighs 1.35kg; the thermal transfer roll model is 267mm × 202mm × 189mm and weighs 2.05kg; the thermal transfer cartridge model is 254mm × 202mm × 177mm and weighs 2.3kg. Portable Option: It supports an optional high-capacity battery, which can meet the power demand of the whole shift. It can be used with a portable bag, turning the desktop printer into a mobile printing device, suitable for on-site printing scenarios such as trolley operations.
