If you need a fast 4-inch printer that is easy to use, easy to deploy and easy to manage, choose the leader of the class — the ZD420. As the next generation in Zebra’s desktop printer line, the ZD420 replaces Zebra’s popular GK Series.
An intuitive user interface with more status icons maximize uptime by making the printer easier than ever to use. You get virtually every modern wired and wireless connectivity option, from USB, auto-sensing serial or 10/100 Ethernet to 802.11ac WLAN and Bluetooth 4.1. With support for both EPL and ZPL, as well as many non-Zebra printer languages, deployment and upgrading is fast and easy — just unplug your existing printer, plug in the ZD420 and you’re back up and running. With a movable media sensor, the ZD420 supports more types of media and you can easily add new connectivity and media handling options whenever you need them, right on site — serial or Ethernet, plus a peeler or a cutter.
Using the included Print Touch tag (NFC), workers can pair a compatible mobile device in a split second. You can monitor and manage all your ZD420 printers from the cloud, for unsurpassed management simplicity. The ZD420 runs Link-OS and is supported by our powerful Print DNA suite of Applications, Utilities and Developer Tools that give our printers better performance, simplified remote manageability, and easier integration. And our optional Zebra OneCare SV service plan provides the right level of service at the right price to help you protect your printers and avoid unexpected expenses.
Bluetooth operates at frequencies between 2400 and 2483.5 MHz (including guard bands 2 MHz wide at the bottom end and 3.5 MHz wide at the top). This is in the globally unlicensed (but not unregulated) Industrial, Scientific and Medical (ISM) 2.4 GHz short-range radio frequency band. Bluetooth uses a radio technology called frequency-hopping spread spectrum. Bluetooth divides transmitted data into packets, and transmits each packet on one of 79 designated Bluetooth channels. Each channel has a bandwidth of 1 MHz. Bluetooth 4.0 uses 2 MHz spacing, which accommodates 40 channels. The first channel starts at 2402 MHz and continues up to 2480 MHz in 1 MHz steps. It usually performs 1600 hops per second, with Adaptive Frequency-Hopping (AFH) enabled.
USB, short for Universal Serial Bus, is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices.USB was designed to standardise the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as serial and parallel ports, as well as separate power chargers for portable devices.
Barcode printing in 203 DPI is great for text, numbers, and codes, but may appear a bit grainy or pixelated. You can improve the print quality of a barcode printed in 200 DPI by making the barcode physically larger on your label, but you may not have enough space to do this on your label. If you decide to do this, please note that each barcode must be scaled proportionately, since the aspect ratio of each barcode is strictly defined by each barcode symbology.203 DPI Printers are the fastest barcode printers and are suitable for high volume applications.
Direct thermal printing requires a heat sensitive label material. The print head elements come into direct contact with the heat sensitive material where the heat from the elements causes a color change in the material to create the printed image. If an organisation is only going to print direct thermal, there are printers available that only have direct thermal capability. These printers are generally less costly to purchase because they do not contain any of the hardware necessary for driving and controlling ribbon. Eliminating the ribbon and ribbon hardware components also results in a less complex printer with fewer parts to wear and/or break, resulting in lower service costs and less downtime over the life of the printer.
A Real Time Clock is a computer clock that keeps track of the current time. With regards to printing, it allows the user to automatically print the time and date on labels, which is of particular use to businesses that need to keep track of time sensitive information.
