© Cengage Learning 2013 A+ Guide to Hardware, Sixth Edition2 Objectives Learn about printer types and features Learn how to install printers and share a printers and how to manage printer features, add-on devices, and the printer queue Learn about routine maintenance tasks necessary to support printers Learn how to troubleshoot printer problems
© Cengage Learning 2013 A+ Guide to Hardware, Sixth Edition3 Printer Types and Features To Configure, Repair, and Maintain printers –Requires knowledge of printer types and features Understanding how a printer works –Helps in logically diagnosing and resolving printer problems
© Cengage Learning 2013 Types of Printers Major categories: –Laser, inkjet (ink dispersion), thermal printers, and impact printers A+ Guide to Hardware, Sixth Edition4 Figure 12-1 Okidata C3200n color laser printer
© Cengage Learning 2013 Laser Printers Laser printer: electrophotographic printer –Uses mechanical, electrical, and optical technologies –Capable of handling and printing large volumes quickly and continuously –Printer that is able to print on both sides of paper is called a duplex printer (double-sided printer) How laser printers work: –Toner placed on electrically charged rotating drum –Toner deposited on paper moving at drum speed –Toner cartridge needs replacing most often –There are 7 steps in the laser printing process A+ Guide to Hardware, Sixth Edition5
© Cengage Learning 2013 Laser Printers Seven steps in laser printing: –Processing image: bitmap of final page stored in memory –Conditioning: drum surface charged to -600 V –Writing: laser beam writes -100 V (discharge) image to drum surface –Developing: toner (-300 V) applied to -100 V areas of the drum –Transferring: toner drawn off drum and onto (positively charged) paper –Fusing: heat (melts) and pressure(roller presses) fuse toner to paper –Cleaning: drum cleaned of residual toner and charge A+ Guide to Hardware, Sixth Edition6
© Cengage Learning 2013 A+ Guide to Hardware, Sixth Edition7 Inkjet Printers Overview of inkjet printer technology –Uses a type of ink-dispersion printing Older inkjet printers didnt provide high-quality resolution of laser printers. Todays are photo quality –Print head moves across paper One line of text created with each pass –Ink applied to paper using matrix of small dots Plates with magnetic charge direct path to the page –Different types of inkjets form droplets of ink in different ways

© Cengage Learning 2013 Impact Printers Guidelines for maintaining print heads: –Keep the printer in a cool, well-ventilated area –Do not print over 50 to 75 pages without a cool down A+ Guide to Hardware, Sixth Edition9 Figure 12-6 Keep the print head of a dot matrix printer as cool as possible so that it will last longer
© Cengage Learning 2013 A+ Guide to Hardware, Sixth Edition10 Impact Printers Overview of impact printer technology –Best known impact printer: dot matrix printer –A print head moves across width of the paper –Pins are used to print matrix of dots on the page Pins shoot against a cloth ribbon (ink and lubrication) Ribbon impacts paper and deposits ink Dot matrix printer technology advantages: –Continuous tractor feed allows event and data logging –Can use carbon paper: print multiple copies –Extremely durable Last forever if maintained, but usually not worth fixing
© Cengage Learning 2013 Thermal Printers Use heat to create an image Two types of thermal printers: –Direct thermal printer Burns dots onto special coated paper (thermal paper) Often used as receipt printers –Thermal transfer printer Uses a ribbon that contains wax-based ink Heating element melts ribbon onto thermal paper Used to print receipts, bar code labels, clothing labels, or container labels Reliable and easy to maintain A+ Guide to Hardware, Sixth Edition11
© Cengage Learning 2013 A+ Guide to Hardware, Sixth Edition12 Using Windows to Install, Share, and Manage Printers Printers can connect to a single computer or a network –Local printer attached to a PC using a port or wireless connection –Network printer has an Ethernet port to connect directly or uses Wi-Fi to connect to an access point OS compatible print drivers required –Use 32-bit drivers for a 32-bit OS and 64-bit drivers for a 64-bit OS –Windows 7 has many drivers built in or drivers can be downloaded from manufacturers website

© Cengage Learning 2013 Installing A Local or Network Printer Ways to install a local USB printer –Plug in USB printer: Windows 7/Vista installs printer automatically –Launch the installation program Installing a non-USB local printer or network printer using Windows 7/Vista –Verify printer on and available –In Windows 7 Control Panel click Devices and Printers A+ Guide to Hardware, Sixth Edition14
© Cengage Learning 2013 Installing A Local or Network Printer Installing a non-USB local printer or network printer using Windows 7/Vista (contd) –Click Add a printer and select the type of printer Local or Network –Windows searches for available printers Select printer from the list and click Next –Tell Windows where to find the printer drivers –Follow the wizard to install the printer –Send a test page to ensure proper setup A test page can be sent anytime through the Printer Properties dialog box A+ Guide to Hardware, Sixth Edition15
© Cengage Learning 2013 Sharing an Installed Printer Windows 7: make sure Turn on file and printer sharing is selected General steps for Windows –Open the printers Properties dialog box, select Sharing –Select Share this printer, enter name for the printer –Make drivers available in Additional Drivers window 32-bit operating systems: select x86 64-bit operating systems: select x64 A+ Guide to Hardware, Sixth Edition16
© Cengage Learning 2013 Installing a Shared Printer In Windows, make sure to Turn on file and printer sharing Two ways to install a shared printer on a remote computer –Use Windows 7 Devices and Printers window –Use Windows Explorer, the Network, or My Network Places window A+ Guide to Hardware, Sixth Edition17 Figure Install a shared printer using Windows Explorer
© Cengage Learning 2013 A+ Guide to Hardware, Sixth Edition18 Managing the Printer Queue Spooling: process of queuing print requests from application –Print spooler: print queue To manage print queue: double-click the printer icon in Windows 7 Devices and Printers window –If the printer reports a problem with printing, will be displayed as the status for the first job in the queue –To cancel a print job, right-click the job and select Cancel from shortcut menu To cancel all print job, click Printer and select Cancel All Documents
