Unboxing and Initial Impressions

Upon unboxing the Zebra ZD420, the first thing that struck me was its modern, matte gray design with yellow accents. This is a significant departure from the creamish gray and green color scheme of previous models. The updated look is sleek and professional.

The rear panel of the ZD420 provides several connectivity options. It includes a power supply, a USB port, and a slot for additional configurations such as Ethernet or serial connections. This versatility ensures compatibility with diverse systems and network setups. The auxiliary USB port's purpose remains unclear, but it hints at further customization.

Inside the Printer: Mechanics and Features

Opening the printer reveals the thermal print head, available in 203 and 300 dpi resolutions. My review unit is the 203 dpi version. The label holder uses a dynamic spring mechanism that's easily adjustable, preventing label jams. The adjustable sensor allows for use with various label types and sizes.

The platen roller is easily accessible, facilitating quick label loading. The printer's use of non-proprietary labels is a major advantage. It simplifies the labeling process by eliminating the need for specialized labels or punch tools.

Bluetooth and Mobile Printing

While Android functionality is excellent, printing directly from the eBay app proved difficult. A workaround involves saving the label to your phone's files and then sending it to the printer, which is an additional step.

Network Setup and App Functionality

The Zebra Printer Setup Utility app simplifies network configuration. While it doesn't support WPS, you can manually enter network credentials via the app for wireless setup. The app also allows you to adjust print settings (quality, speed, darkness), and these settings are stored within the printer itself.

iOS Compatibility and Conclusion

While the ZD420 claims iOS compatibility, I encountered issues printing directly from an iOS device. This may be a user error, or it may represent a current limitation needing attention from Zebra. Further testing is required to determine the precise cause.

Overall, the Zebra ZD420 is a high-quality printer with excellent Android compatibility and versatile features. Its non-proprietary label support, mobile connectivity, and app-based configuration tools are significant advantages.
