COMPUTER TROUBLESHOOTING
Chapter 11:
Supporting Printers & Scanner

2. Objectives
In this chapter, you will learn:
 How printers work
 How to install printers and share them over a
local area network
 How to troubleshoot printer problems

3. How Printers Work
 Local Printers (peer to peer)
 Connect directly to computer
 Parallel port, serial port, USB port, infrared connection,
etc Wireless
 Network Printers
 Various options on hardware
 Impact Printers (striking the paper)
 Non-impact printers (Laser printer / Inkjet printer)

4. Laser Printers
 Interaction of mechanical, electrical and
optical technologies
 Use toner, a dry, powdered electrically
charged ink
 Performs various steps in printing process

5. How a Laser Printer Works

6. Inkjet Printers
 Ink dispersion printing
 Inexpensive color printing
 Can provide photo-quality output
 Quality of paper affects quality of output

7. How an Inkjet Printer Works

8. Dot-Matrix Printers
 Less expensive
 Lesser quality output
 Impact printer
 Multicopy documents
 Print head moves across the page
 Pins print a matrix of dots by striking printer
ribbon

9. Thermal Printer and Solid Ink Printers
 Newer technology
 Non-impact printers using heat
 Thermal printers use wax-based ink
 Used in retail for bar codes and price tags
 Direct thermal printing
 Thermal wax transfer printing
 Thermal dye sublimation technology

10. Installing and Sharing a Printer
 Local printer
 A printer connected to a computer by way of a
port on the computer
 Network printer
 A printer accessed by way of a network
 Default printer
 The printer used by Windows for printing unless
another printer is selected

11. Sharing a Printer with Others in a
Workgroup
 Open Printers window
(Start/Settings/Printers)
 Right click the printer to share
 Select Sharing (If grayed out, File and
Printer Sharing is not available)
 In Properties dialog box select Shared As
and give printer a name
 Click OK

12. Other Methods of Sharing Printers
over a Network
 Regular printer can be attached to a PC
using a port on the PC
 That PC can share printer with the network
 Network printer with embedded logic to
manage network communication can be
connected directly to a network with its own
NIC
 A dedicated device or computer called a print
server can control several printers connected
to a network

13. Printer Maintenance
 On Web site, look for
 Online documentation
 Knowledge base of common problems and
solutions
 Updated device drivers
 Flash BIOS updates
 Replacement parts
 Printer maintenance kits
 Additional software

14. General Printer Troubleshooting
 Isolate problem to one of the following
factors:
 Application attempting to use the printer
 The OS and printer drivers
 Connectivity between printer and PC
 The printer itself
 Verify that a printer self-test page can
print
 Check for a problem with the printer
cable
