2. Laser Printers Use electrophotographic technologies The drum is coated with a light-sensitve material The image is written to the drum with a laser The drum then picks up toner in the shape of the image. It is then deposited on the paper and fused onto the paper with heat.

3. Impact Printers Can make carbon copies (NCR Forms) The ribbons tend to be cheaper to use than ink cartridges or toner. Can make carbon copies (NCR Forms) The ribbons tend to be cheaper to use than ink cartridges or toner.

4. Inkjets Spray ink onto the paper to form images. Quality is measured in dots per inch. DPI Nozzles can clog Spray ink onto the paper to form images. Quality is measured in dots per inch. DPI Nozzles can clog

5. Piezoelectric Printers Are rare Use a vibrating crystal to control ink flow. Are rare Use a vibrating crystal to control ink flow.

7. Solid ink printers Produce vivid colors We have one in this room. Produce vivid colors We have one in this room.

8. Thermal Printers Are used to avoid having to worry about ink or toner. Often used in cash registers and gas pumps to print receipts. Are used to avoid having to worry about ink or toner. Often used in cash registers and gas pumps to print receipts.

9. Scanners Pages scanned are brought in as images You cannot edit them as a word processing file OCR (Optical Character Recognition) software can solve this problem. Drum scanners produce the highest quality images while handheld and flatbed scanners are easier on the originals.

10. All-In-One Devices Combine Fax, Scanning and Printing in One Device

11. Firewire Called the IEEE1394 Also called I.Link Can use up to 63 devices on one port. Called the IEEE1394 Also called I.Link Can use up to 63 devices on one port.

12. Parallel Printer Ports Seldom used anymore. Newer machines may not have one. Met the IEEE1284 Standard. Bidirectional communications from IEEE1284 are ECP and EPP. The return communications were for low ink warnings etc. Some early webcams used the parallel port. Seldom used anymore. Newer machines may not have one. Met the IEEE1284 Standard.

13. That’s It! Good luck on the test!
