Transcript of "Ch 6"

  1. 1. Printers What is a line printer? p. 304 Fig. 6-18 Next  High-speed impact printer that prints entire line at a time  Speed measured in lines per minute (lpm)  Band printer prints fully formed characters using a hammer mechanism  Shuttle-matrix printer is high-speed printer that works like dot-matrix printer
  2. 2. Printers What is an ink-jet printer? p. 305 Fig. 6-19 Next  A type of nonimpact printer that sprays tiny drops of liquid ink onto paper  Nonimpact printer forms characters and graphics without striking paper  Prints in black-and-white or color on a variety of paper types
  3. 3. Printers What is the resolution of a printer? p. 306 Fig. 6-20 Next  Sharpness and clarity  Measured by number of dots per inch (dpi) printer can output
  4. 4. Printers How does an ink-jet printer work? p. 307 Fig. 6-21 Next Step 1. A small resistor heats the ink, causing the ink to boil and form a vapor bubble. Step 2. The vapor bubble forces the ink through the nozzle. Step 3. Ink drops onto the paper. Step 4. As the vapor bubble collapses, fresh ink is drawn into the firing chamber. print cartridge print head nozzle firing chamber nozzlebubble resistor ink ink ink dot paper
