  1. Barcode printer

    File 2008TaipeiPack Linx Barcode Printer.jpg thumb 250px A barcode printer A barcode printer or bar code printer is a computer peripheral for printing barcode labels or tags that can be attached to physical objects. Barcode printers are commonly used to label cartons before shipment, or to label retail items with Universal Product Code UPC s or European Article Number EAN s. The most common barcode printers employ one of two different printing technologies. Thermal printer Direct thermal printer s use a printhead to generate heat that causes a chemical reaction in specially designed paper that turns the paper black. Thermal transfer printer s also use heat, but instead of reacting the paper, the heat melts a wax y or resin substance on a ribbon that runs over the label or tag material. The heat transfers ink from the ribbon to the paper. Direct thermal printers are generally less expensive, but they produce labels that can become illegible if exposed to heat, direct sunlight, or chemical vapors. Barcode printers are designed for different markets. Industrial barcode printers are used in large warehouses and manufacturing facilities. They have large paper capacities, operate faster and have a longer service life . For retail and office environments, desktop barcode printers are most common.

  1. Veris printer

    The Veris printer ref http graphics.kodak.com US en Product consumables proofing media inkjet media Veris default.htm Kodak Veris Proofing Media ref is a medium format 4 up 1500 DPI color inkjet printer manufactured by the Graphic Communications Group of Eastman Kodak , which is used for digital Prepress proofing . A refinement of the Iris printer , the Veris also uses a continuous flow ink system to produce continuous tone output on specially designed media. Unlike most inkjet printers which fire drops only when needed, the Veris uses eight 1 micrometer glass jets that operate continuously under high pressure, vibrated by a piezoelectric crystal to produce drops at a 1 MHz rate, or 8 million drops per second in total. Drops that are not needed to form the image are deflected electrostatically into a waste collection system, and individual drops can be directed to a specific position on the media. The Veris prints with the same quality of the Iris, only faster because of the larger number of jets or pens as they are called . History The Veris printer was originally developed by Iris Graphics, which was acquired by Scitex and later merged with Creo Creo Products Inc. . In 2005 Creo was purchased by Kodak. The Veris was first released in 2004 and production of the Veris ended in 2008, although the product is still supported and in use as of 2010.

  1. LED printer

    Image Kodak LED Printer 20R.jpg thumb Kodak LED printer Image LED printhead.JPG thumb Oki LED printhead An LED printer is a type of computer printer. LED technology uses a light emitting diode array as a light source in the printhead. The LED bar pulse flashes across the entire page width and creates the image on the print drum or belt as it moves past. LED s are more efficient and reliable than conventional laser printers, since they have fewer moving parts . Depending on design, LED printers can have faster rates of print than some laser based designs, and are generally cheaper to manufacture. Laser systems rely on elaborate combinations of rotating mirrors and lenses that must remain in alignment throughout their use. The laser scans from one end of a line to another, then starts on the next line. Unlike laser printer s, an LED printhead has no moving parts. Although used differently, a similar principle was used in Nintendo s Virtual Boy . LED printing was invented by Casio . ref http www.pctechguide.com 52Lasers LED printers.htm Guides Input & Output Laser Printers PC Technology Guide Bot generated title ref References reflist http okidata.printermalls.com led versus laser.htm Okidata LED Versus Laser Printers Category Computer printers Category Non impact printing de LED Drucker fr Imprimante DEL ja LED ru Compu hardware stub ...   more details
