1 PC Maintenance: Preparing for A+ Certification Chapter 18: Working with Printers

2 Chapter 18 Objectives Identify basic printer functions Identify basic printer functions Distinguish between classes of printers Distinguish between classes of printers Explain printer technologies Explain printer technologies Explain the laser printing process Explain the laser printing process Install and manage printer drivers in Windows Install and manage printer drivers in Windows View and install Windows fonts View and install Windows fonts Troubleshoot printer problems Troubleshoot printer problems

3 Basic Printing Functions Receive data from the PC through an I/O interface Receive data from the PC through an I/O interface Store the data in printer RAM Store the data in printer RAM Convert the data into print instructions Convert the data into print instructions Feed the paper in and out Feed the paper in and out Store and dispense ink or toner Store and dispense ink or toner Transfer the image onto the paper Transfer the image onto the paper

4 Line Printer Print job is still spooling to the printer as the page begins printing Print job is still spooling to the printer as the page begins printing Requires very little RAM of its own Requires very little RAM of its own Examples: Ink-jet, dot matrix, daisywheel Examples: Ink-jet, dot matrix, daisywheel

5 Line Printer

6 Page Printer Entire page collects in printer RAM, then is transferred to the paper Entire page collects in printer RAM, then is transferred to the paper Requires more RAM than a line printer because it must hold more data at a time Requires more RAM than a line printer because it must hold more data at a time Examples: Laser, LED Examples: Laser, LED

8 Ink or Toner Liquid ink: Sprayed onto paper Liquid ink: Sprayed onto paper Dry toner: Transferred to paper with electrical charge and then fused (melted) to the paper with heat Dry toner: Transferred to paper with electrical charge and then fused (melted) to the paper with heat Inked ribbon: Pins or hammers strike the ribbon, leaving a mark on the paper behind it Inked ribbon: Pins or hammers strike the ribbon, leaving a mark on the paper behind it

9 Impact and Non-Impact Impact printer strikes a ribbon physically. Only an impact printer is able to print on multi-part forms (such as carbon paper) Impact printer strikes a ribbon physically. Only an impact printer is able to print on multi-part forms (such as carbon paper) Inkjet, Daisywheel Inkjet, Daisywheel Non-impact printer does not use physical force to place the image on the page. Multiple copies must be printed individually. Non-impact printer does not use physical force to place the image on the page. Multiple copies must be printed individually.
