Zebra’s G-Series GX printers pair the fastest print speeds with the most complete feature set of our desktop printer lineup. Innovative label, receipt and tag-handling capabilities enable the flexibility you need. Offering top print quality and a variety of connectivity options, the Zebra GX printers support the widest range of applications and can be integrated into almost any environment so that you can improve efficiency and profitability, save time and reduce operator training. As the fastest direct thermal printer in Zebra’s desktop product family, the GX420D is ideal for applications with a shorter shelf life that require faster speeds and enhanced network connectivity.
An auto-cutter will separate the paper from the roll after each receipt is printed. When speed and reliability are essential, receipt printers with auto-cutters are often a defining factor especially in kitchen and order picking applications. With an auto-cutter you ensure that each receipt is completely separated which helps reduce paper jams and time spent with poorly torn receipts.
Ethernet stations communicate by sending each other data packets: blocks of data individually sent and delivered. As with other IEEE 802 LANs, each Ethernet station is given a 48-bit MAC address. The MAC addresses are used to specify both the destination and the source of each data packet. Ethernet establishes link level connections, which can be defined using both the destination and source addresses. On reception of a transmission, the receiver uses the destination address to determine whether the transmission is relevant to the station or should be ignored. Network interfaces normally do not accept packets addressed to other Ethernet stations.
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.
In computing, a serial port is a serial communication interface through which information transfers in or out one bit at a time (in contrast to a parallel port)
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.
