 * == ‍‍‍‍Impact Printers‍‍‍‍ ==
 * Also known as dot-matrix printers.
 * Not as popular as the other printers because they are noisy and slow.
 * Uses a print head that contains 9 or 24 pins to strike the paper to print.
 * Impact printers use a tractor feed or friction feed.
 * A tractor feed uses a sprocket to turn and pull the paper through the feed.
 * Friction feed uses a single sheet of paper and pulls it through the printer on a tight roller.
 * Impact printers usually use a serial or parallel interface connection.
 * == Inkjet Printers ==
 * Also known as ink dispersion printing tech.
 * Ink is forced through the nozzles through two different methods. Thermal Bubble and Piezoelectric Bubble
 * Thermal Bubble tech heats the ink, creating a bubble. The bubble protrudes through the nozzle and sprays on the paper.
 * Piezoelectric Tech uses a piezo crystal behind each nozzle. An electric current vibrates the nozzle pushing the ink into the paper.
 * Inkjet Printers use ink cartridges which have print heads that the ink comes through.
 * ‍‍‍‍Dithering‍‍‍‍ creates a darker or lighter shade of a color by varying pattern of dots and density of dots.
 * Use two different paper paths: Straight-through and Curved.


 * == Laser Printers ==
 * Produces high quality print outs
 * Produces images by using an electrophotographic process.
 * Components of a laser printer are
 * toner cartridge
 * laser scannning assembly
 * power supplies
 * paper control and transport assembly
 * transfer corona assembly
 * fusing assembly
 * electronic control package

 * == Thermal Printers ==
 * Produce output through heat
 * Three different methods:
 * Thermal wax transfer [[image:https://encrypted-tbn2.google.com/images?q=tbn:ANd9GcThaBb7cMebCrx2uovRNG5KOuiIH-p9m81q6B7VopRJoC1hLv38zw width="142" height="142" caption="Thermal Wax"]]
 * Direct thermal [[image:https://encrypted-tbn0.google.com/images?q=tbn:ANd9GcQs58UtfZ4aTHylnHidFUND7zCMqb-zaO8TDYPN9pHm2phIm4UZ-Q width="228" height="221" caption="Direct thermal printer"]]
 * Thermal autochrome: uses special paper in which cyan, magenta, and yellow are embedded in [[image:https://encrypted-tbn2.google.com/images?q=tbn:ANd9GcQ1JMW4JcVyOfr2lBWRTx4SMfikXabi18qXHQ2cJNHjglQ9zm5f width="260" height="194"]]
 * == Other Printers ==
 * Plotters- a pen based output device that produces line images. Used to create engineering documents [[image:https://encrypted-tbn1.google.com/images?q=tbn:ANd9GcSedGmpvpb7FrpuZfCegFvYN5tW-tGXStq7dLBv-6RWVBWoPmK8Hg width="241" height="209" caption="Plotter"]]
 * Solid ink printers- uses sticks of wax that are melted to create the ink for printing [[image:https://encrypted-tbn0.google.com/images?q=tbn:ANd9GcSQZXowPfY7l3j9p1Dj2zaLTHS3EsTlXSLWyr1dDYJIFlNBkpYuaA width="269" height="187" caption="Solid ink Printer"]]
 * Dye sublimation printers- Use solid dye on a roll or ribbon to print an image [[image:https://encrypted-tbn1.google.com/images?q=tbn:ANd9GcSLs1svgE42GxKTgbMnx6634YgnnNt88V5rexlUb3IjOB7JVfaO width="225" height="225" caption="Dye Sublimation"]]
 * == Local printer vs. Network printer ==
 * A local printer is a printer that is directly connected to a computer through a USB or SATA connection
 * A network printer is a printer that is connected into a network server. This type of printer is used within businesses and office buildings.[[image:essentialsstudyguide/network_printer.jpg width="308" height="186" caption="Network Printer" link="@http://www.google.com/imgres?um=1&hl=en&biw=1024&bih=571&tbm=isch&tbnid=UTplA9Goc5GXAM:&imgrefurl=http://thelightmatters.com/equipment/network-printing-canon-pixma-pro9000-mark-ii/&docid=rev0KEE3OFchoM&imgurl=http://thelightmatters.com/wp-content/uploads/2011/04/printer.jpg&w=697&h=400&ei=VJtXT9rRDoLr0gGqqfGlDw&zoom=1&iact=hc&vpx=570&vpy=206&dur=1166&hovh=170&hovw=297&tx=174&ty=83&sig=109580032503312504183&page=2&tbnh=95&tbnw=165&start=12&ndsp=20&ved=1t:429,r:8,s:12"]]
 * == Printer Drivers ==
 * Most printers connect through USB, so they are recognized automatically through Windows.
 * If your printer is recognized by Windows, it will begin to install the appropriate drivers.
 * If your printer is not recognized by Windows you can manually install the drivers that you received with the printer.
 * == Consumables ==
 * With printers you have to replace the paper and ink.
 * Depending on the type of printer you have, you will have to buy certain paper and ink for that printer.
 * There are different types of ink like powder, liquid, and wax, so be certain you buy the right ink for your type of printer.
