Zebra’s G-Series™ GC420™ printers offer professional printing for any budget. These affordable, easy-to-use printers are ideal for a variety of basic labeling applications. Although value priced, these printers are still engineered for reliability and longevity. Like all G-Series printers, the GC420 has a dual-wall framed construction and all-metal printhead to reduce replacement parts and decrease printer downtime.
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)
A parallel port is a type of interface found on computers (personal and otherwise) for connecting peripherals. In computing, a parallel port is a parallel communication physical interface. It is also known as a printer port or Centronics port. It was an industry de facto standard for many years, and was finally standardized as IEEE 1284 in the late 1990s, which defined the Enhanced Parallel Port (EPP) and Extended Capability Port (ECP) bi-directional versions. Today, the parallel port interface is seeing decreasing use because of the rise of Universal Serial Bus (USB) devices, along with network printing using Ethernet. The parallel port interface was originally known as the Parallel Printer Adapter on IBM PC-compatible computers. It was primarily designed to operate a line printer that used IBM's 8-bit extended ASCII character set to print text, but could also be used to adapt other peripherals. Graphical printers, along with a host of other devices, have been designed to communicate with the system.
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.
Roll Dispensers provide convenient and trouble-free feeding of media to printers, and are available for media of various sizes. They are a stable, accurate and reliable guide for feeding continuous roll media into your printer.
