4. HOW PRINTERS AND SCANNERS WORK Printers and scanner can connect to a computer by way of a USB port, parallel port, serial port, wireless connection (Bluetooth, infrared, or WiFi), IEEE 1394 (FireWire), port, SCSI port, PC card, or ExpressCard connection, or by a network. Printer can have a variety of options There are two major type of printer –Impact printer –Nonimpact printer Copyright © 2007 - CIST 4 A+ Tip: The A+ Ess. Exam expects you to know that printers and sc anners can connect using these interfaces: parallel, network, USB, SCSI, IEEE 1394 (FireWire), and wireless (Bluetooth, 802.11, and infrared). Notes: if you can afford it, the best practice is to purchase one machine for one purpose instead of bundling many functions into a single machine. Routine maintenance and troubleshooting are easier and less expensive on single-purpose machine, although the initial cost is higher.

5. LASER PRINTERS A laser printer is a type of electrophotographic printer that can range from a small, personal desktop model to a large, network printer capable of handling and printing large volumes continuously Copyright © 2007 - CIST 5 A+ ExamTip: The A+ Ess. Exam expects you to be familiar with these types of printers: laser, inkjet, solid ink, thermal, and impact.

6. LASER PRINTERS Copyright © 2007 - CIST 6 A+ Exam Tip: The A+ Ess. Exam expects you to know the six steps in the printing process fro a laser printer.

7. HOW LASER PRINTERS WORKS 1. Cleaning. The drum is cleaned of any residual toner and electrical charge 2. Conditioning. The drum is conditioned to contain a high electrical charge. 3. Writing. A laser beam discharges the high charge down to a lower charge, only in those places where toner is to go. 4. Developing. Toner is placed onto the drum where the charge has been reduced. 5. Transferring. A strong electrical charge draws the toner of the drum onto the paper. This is the first step that take place outside the cartridge. 6. Fusing. Heat and pressure fuse the toner to the paper Copyright © 2007 - CIST 7

8. INKJET PRINTERS Inkjet printers use a type of ink-dispersion printing Inexpensive color printing Can provide photo-quality output Quality of paper affects quality of output Today inkjet printer can use up to 4800 x 1200 dpi Slower than laser printer Use a print head to move across the paper The most popular technology is bubble-jet Inkjet printer include one or more ink cartridges Copyright © 2007 - CIST 8

9. INKJET PRINTERS Copyright © 2007 - CIST 9

10. DOT MATRIX PRINTERS Almost nonexistent now, it was replace by inkjet and laser printer The two reasons you still see some around 1.Impact printers and can print multicopy documents 2.They last long forever Less expensive Lesser quality output Print head moves across the page Pins print a matrix of dots by striking printer ribbon Copyright © 2007 - CIST 10

11. THERMAL PRINTERS Newer technology Non-impact printers using heat to produce print output Thermal printers use wax-based ink Used in retail for bar codes and price tags –Direct thermal printing –Thermal wax transfer printing One variation of thermal printing use thermal dye sublimation technology –A dye-sublimation printer use solid dyes embedded on different transparent film Copyright © 2007 - CIST 11

12. SOLID INK PRINTERS Use ink store in solid blocks, Xerox calls color stick The sticks or block are easy to handle and several can be inserted The design is simple, quality is excellent Easy to setup and maintain The greatest disadvantage is the time to takes for the print head to heat up to begin a job Copyright © 2007 - CIST 12 Printer Manufacturer Web SitePrinter Manufacturer Web Site Brotherwww.brother.comOkidatawww.okidata.com Canonwww.canon.comSATOwww.satoamerica.com Hewlett-Packardwww.hp.comSeiko Epsonwww.epson.com IBMwww.ibm.comTally Genicomwww.tallygenicom.com Lexmarkwww.lexmark.comXeroxwww.xerox.com

21. USING A SHARED PRITNER Another ways to install a shred printer is to first use My Network Place or Neighborhood: Copyright © 2007 - CIST 21

22. OTHER METHODS OF SHARING PRITNERS OVER A NETWORK The three ways to make a printer available on a network are listed here: A regular printer can be attached to a PC using a port on the PC, and then that PC can share the printer with the network. A 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. Copyright © 2007 - CIST 22

23. OTHER METHODS OF SHARING PRITNERS OVER A NETWORK If you don’t have directions, do the following : 1. Download the printer drivers from the manufacturer’s Web site 2. Start a wizard to add a new printer. Select the option to install a local printer but do not as Windows to automatically detect the printer. 3. Choose Create a new port. Select Standard TCP/IP Port. Click Next twice. 4. Enter the IP address of the printer, click Next. 5. Click Have Disk and point to the drivers. 6. When ask you can make the printer to be a default printer. When ask you can select Yes to print a test page. Click Finish. Copyright © 2007 - CIST 23 Notes: to know the IP address of a network printer, look in the printer documentation. Or you can press a key on the front panel of the printer to instruct it to print setup information about the printer, which should include its IP address. To know which key to press to print the setup report, see the printer documentation.

39. Copyright © 2007 - CIST 39 Summary The two most popular types of printers are laser and inkjet. Other types of printers are solid ink, dye sublimation, thermal printers, and dot matrix. Laser printers produce the highest quality, followed by inkjet printers. Dot matrix printers have the advantage of being able to print multicopy documents. The six steps that a laser printer perform to print are cleaning, conditioning, writing, developing, transferring, and fusing. The first four steps take place inside the removable toner cartridge. Inkjet printers print by shooting ionized ink at a sheet of paper. The nozzles of an inkjet printer tend to clog or dry out, especially when the printer remains unused. The nozzles can be cleaned automatically by means of printer software or buttons on the front panel of the printer. Dot matrix print by projecting pins from the print head against an inked ribbon that deposit ink on the paper. Three types of scanners are flat-bed, sheet-fed, and portable scanners.

40. Copyright © 2007 - CIST 40 Summary A printer is installed as a local printer connected directly to a computer, a network printer that works as a device on the network, or a network printer connected to a printer server. A local printer can be shared so that others can use it as a resource on the network. Printers can process print jobs using PostScript, PCL (Printer Control Language), or GDI input. In addition, printers can receive raw data that can be printed with no processing. Windows manages and configures a printer using the Windows XP Printers and Faxes windows or the Windows 2000 or Windows 9x/Me printers window. Routine maintenance and cleaning help a printer or scanner to last loner and work better. When troubleshooting printers, first isolate the problem. Narrow the source to the printer, cable, PC hardware, operating system including the device driver, application software, or network. Test page printed directly at the printer or within Windows can help narrow down the source of the problem.
