14. Laser Printers • See Handout

15. Impact Printer • Print head strikes inked ribbon • Dot matrix • Print head with pins • Daisy wheel • Wheel with characters • A: Cheap ribbon, continuous feed paper, can print on carbon copy paper • D: Noisy, low-resolution, slow

16. Inkjet Printers • Ink cartridges spray liquid ink onto paper through nozzles • Thermal- steam forces ink out • Piezoelectric- vibration controls ink flow • Let ink dry for 15 seconds • A: low cost, high res, quick to print • D: nozzles can clog, ink $$, ink wet after print

17. Thermal Printer • Receipt printer, old fax machines • Waxy paper • Turns black when heated • A: Small, few moving parts, longer life • D: Paper $$, paper storage issues (temp & life), poor graphics

18. Dye-Sublimation Printers • High-quality photos • Sheets of ink

19. Solid Ink Printers • High quality images • Solid sticks of ink (no waste) • Ink melts • Sprayed through nozzles to a drum • Drum transfers to paper • A: Vibrant color prints , easy to use, many paper types, faster than inkjet • D: Printer & ink are $$$, slow to warm up

20. Printer Comparison

21. Review • Which printer can you use carbon-copy paper in? • Impact • Which printer can print photo quality pictures and is inexpensive? • Inkjet • Which printer has the most inexpensive consumable? • Impact • Which printer has vivid color prints, but is expensive & warms up slowly? • Solid ink

22. Review • A drum, fuser, and toner are in what printer? • Laser • What printer takes liquid ink cartridges? • Inkjet • Which printer most environmentally friendly? • Solid ink • Which printer has nozzle that can get clogged? • Inkjet

23. Printer Installation & Configuration • Describe how to set up a printer. • Explain how to power and connect the device using a local or network port. • Describe how to install and update the device driver, firmware, and RAM. • Identify configuration options and default settings. • Describe how to optimize printer performance. • Describe how to print a test page. • Describe how to share a printer
