ZD420c 4-Inch Thermal Transfer Printer

Groundbreaking Ease of Use

The ZD420c is loaded with features that make it the easiest printer to use in its class. The ZD420c is the only thermal printer to offer a ribbon cartridge that takes just a few seconds to load, with fool-proof one way first-time every-time instant loading. The crypto chip in the ribbon lets you know when the ribbon needs replacing. And with five intuitive status icons — status, pause, data, supplies and network — your workers can see at a glance what to do to keep the ZD420c up, running and available.

Get All the Features You Need Today — and Easily Add the Features You Need Tomorrow

The movable media sensor supports media with off-center black marks, die-cut notches or multiple labels across the width. The printer offers virtually every modern connectivity option, including USB, auto-sensing serial or 10/100 Ethernet, 802.11ac Wi-Fi, Bluetooth 4.1, plus simultaneous support for Wi-Fi and Ethernet. Easily add new communication or media handling options right on site, such as serial or Ethernet connectivity, a peeler and a cutter. Backwards compatibility with existing applications, formats and printer languages allows you to easily upgrade from your aging Zebra LP 2824 Plus — just plug in the ZD420c and you’re back up and running. And with support for Zebra ZPL and EPL printer languages and many non-Zebra languages, it’s easy to upgrade from competitive printers.

Easy to Clean and Sanitize Healthcare Model

Disinfectant-ready plastics and a sealed button interface make the ZD420c-HC easy to clean and disinfect — crucial in hospitals and clinics. The printer fits easily in space constrained pharmacies, labs and nurses stations. And a 300 dpi printing option ensures that even the small labels on specimen containers and prescriptions are highly legible.

Optional Battery for Cordless Operation

The removable desktop battery power option makes it easy to transport the ZD420c printer on a cart for on-the-spot printing, reducing steps, increasing productivity and improving task accuracy. The battery housing mounts securely to the printer base and connecting the battery is as simple as snapping the battery into the housing. And the high-capacity battery can power it all for a full shift — the printer at maximum print speed, along with a peeler, cutter and keyboard.

Link-OS for Unparalleled Ease of Management

With Link-OS, Zebra’s unique printer software platform, you can easily deploy and manage one printer, a group of specific printers or all printers anywhere in the world via the cloud. And a quick tap of an NFC-enabled mobile device on the ZD420 provides access to Zebra’s extensive knowledge base of how-to videos and more for fast issue resolution.
