what is printer??

What's Printer / Printer?This time I will discuss about the printer, gan: DWhat is the printer? Printer or in the Indonesian language Printer is a tool that can display text / images in print paper. Printer is divided into two parts, namely picker (or Indonesian Penggetil) and printing equipment. Picker serves to take the paper out of the tray, which is a place to put paper. Type of printing the printer is divided into several types, namely:
Laser PrinterLaser? Definitely cool tuh! Yep, the way it works is cool, but first hear the explanation dong ... laser printer is a computer peripheral which produces faster general high quality text and graphics on plain paper. Such as digital copiers and multifunction printers, laser printers xerographic printing process but differ from analog photocopiers in the image produced by the direct scanning of a laser beam on the photoreceptor of the printer.Gary Starkweather, inventor of the laser printerA laser beam projecting images to be printed to an electrically charged rotating drum coated with selenium. Photoconductivity allows the charge leak away from the area exposed to light. Dried ink particles are then electrostatically picked up by a drum filled areas, which have not been exposed to light. The drum then prints the image onto paper by direct contact and heat, which melts the ink to the paper.The laser printer was found at Xerox in 1969 by researcher Gary Starkweather. Starkweather disable imaging system and created a spinning drum with 8 mirrored sides, with a laser focused on the drum. Light from the laser would bounce off the spinning drum, sweeping the yard like traveling through a copyist. This hardware was completed in just one or two weeks, but the computer interface and software took almost 3 months to complete.How it works Laser Printers:
Advantages of Laser Printer:

    High print quality
    High print speeds
    Can print on various paper sizes
    Printing price is cheaperLaser Printer Disadvantages:

    Poor print quality photos
    The price is more expensive than the colored laser color InkJetRead more about Laser Printer >>InkJet PrinterHuh? What is that? Like a jet plane? Yep, that's right, it's just not the best. Inkjet printers operate by pushing the variable-sized droplets of liquid ink to almost any size yard. Inkjet printing concept originated from the 20th century, and this technology was first widely developed in the early 1950s. Beginning in 1970 inkjet printer can reproduce digital images generated by computer developed, mainly by Epson, Hewlett-Packard (HP) and Canon.There are two types of technology used for inkjet printer:

    Continuous Inkjet (CIJ)
    This method is used commercially for marking and coding of products and packages. The idea was first patented in 1867 by Lord Kelvin, and the first commercial (medical tape recorder chart) was introduced in 1951 by Siemens.
    In continuous inkjet technology, a high pressure pump directs liquid ink from a reservoir through gunbody and microscopic nozzle, creating a continuous stream of ink droplets via the Plateau-Rayleigh instability. A piezoelectric crystals create such acoustic waves vibrate in gunbody and cause the flow of fluid into droplets at regular intervals - 64,000 to 165,000 droplets per second can be achieved. Ink droplets subjected to an electrostatic field created by a charging electrode they form; field varies according to the desired rate of decrease deflection. This results in a charge, controlled electrostatic variables on each droplet. Charged droplets are separated by one or more uncharged "guard droplets" to minimize electrostatic repulsion between neighboring droplets.

    Continuous InkJet How it works:

    Thermal (thermal DOD inkjet)
    A brand Canon InkJet printer with CMYK cartridges
    Consumer inkjet printers with the most, from companies including Canon, Hewlett-Packard, and Lexmark (but not Epson), using the print cartridges with a series of small rooms each containing a heater, which were built by photolithography.
    The ink used is usually water-based and using one of the pigments or dyes as colorants. The ink used must have a volatile components to form a vapor bubble, otherwise droplet ejection can not occur. Because no special materials are required, the print head is generally cheaper to produce than other inkjet technology. The principle of the thermal inkjet found by Canon engineer Ichiro Endo in August 1977.

    How it works Thermal Inkjet:Excess InkJet Printer:

    Print more subtle
    No need to wait until the ink is hotInkJet Printer Disadvantages:

    Ink price is more expensive
    Many ink cartridges "smart" contains a microchip that communicates on the level of ink to the printer, this may cause the printer displays an error message, or incorrectly informs the user that the ink cartridge is empty.
    Water-soluble ink, paper printed sekecilpun should not be exposed to water, as this may cause the ink blur.
    Inkjet nozzles are very narrow so prone to clogging.Read more about Inkjet Printer >>Solid Ink PrinterSolid ink is a technology used in computer printers and multifunction devices originally created by Tektronix in 1986. After obtaining Xerox Color Printing and Imaging Division of Tektronix in 2000, the solid ink technology to be part of a line of Xerox office printing and imaging products. The initial offer is focused on the graphic arts industry. Phaser III product introduced in 1991 cost $ 10,000 US. As technology improved and costs reduced, the focus switched to printing environments where quality and cost efficiency are important.A Solid Ink Printers Xerox Phaser 8500.Solid ink technology uses solid ink sticks instead of a liquid ink or powdered toner is usually used in the printer. After the ink stick is loaded into the printing device, splinters and used to produce images on paper in a process similar to offset printing. Xerox claims that solid ink printing produces more vibrant colors than other methods, easier to use, it can print on a variety of media, and more environmentally friendly due to reduced waste output. Sticks are non-toxic and safe to handle. In mid 1990, the president of Tektronix actually ate part of a solid ink stick, suggesting that they are safe to handle and may, eat. Media Ink that (at least at the time) made from vegetable oil processed food value.Solid Ink Printer How it works:
Excess Solid Ink Printer:

    Considered excellent print quality with vivid color
    Waste generated Solid Ink Printers fewer than InkJet and Laser
    Can print on any kind of paperDisadvantages Solid Ink Printer:

    Ink on paper easily eroded, so if removed to use the eraser, would erode the ink.
    If the printer to cool, take a few minutes to heat up the ink.

Name sublimation dyes applied for the transition between the solid and gas without going through a liquid stage.Most Dye Sublimation Printers using CMYO color (Cyan Magenta Yellow overcoating), which differs from the more commonly known as CMYK color, namely that the black dye is removed so that a clear overcoating.Printer Sublimssi Excess Mascara:

    Can be used to print photos
    Quick-drying ink in the moldDye Sublimation Printer Disadvantages:

    Because the ink is sublimated gas, it does not spread a small amount before being absorbed by the paper. As a result, the mold is not sharp. For images, this produces a very natural mold, but for other purposes (such as graphic design) This little blurriness is a shortage.
    Dyes wasted very high.Read more about the Dye Sublimation Printer >>Hmm ... So, what kind of printer you use? According to the advantages and disadvantages of each type of printer, whether you want to replace the printer you use?
