The document discusses different types of printers commonly used in computing. It describes impact printers that use an inked ribbon like dot matrix printers, and non-impact printers like inkjet printers that spray ink onto paper and laser printers that use toner and heat to print high quality documents. The document compares factors to consider when choosing a printer like cost, speed, and image quality. It also outlines special purpose high-quality printers used for photos, durable outputs, or large format blueprints.

- 3. 4B-3 Commonly Used Printers • Impact printers – Generate output by striking the paper – Uses an inked ribbon • Non-impact printers – Use methods other than force – Tend to be quiet and fast
- 4. 4B-4 Commonly Used Printers • Dot matrix printers – Impact printer – Used to print to multi-sheet pages – Print head strikes inked ribbon – Line printers – Band printers – Speed measured in characters per second
- 5. 4B-5 Dot Matrix Print Head
- 6. 4B-6 Commonly Used Printers • Ink-jet printers – Non-impact printer – Inexpensive home printer – Color output common using CMYK • Cyan, magenta, yellow, black – Sprays ink onto paper – Speed measured in pages per minute – Quality expressed as dots per inch
- 8. 4B-8 Commonly Used Printers • Laser printer – Non-impact printer – Produces high quality documents – Color or black and white – Print process • Laser draws text on page • Toner sticks to text • Toner melted to page – Speed measured in pages per minute – Quality expressed as dots per inch
- 9. 4B-9 Commonly Used Printers • All-in-one peripherals – Scanner, copier, printer and fax – Popular in home offices – Prices are very reasonable
- 10. 4B-10 Comparing Printers • Determine what you need • Determine what you can spend • Initial cost • Cost of operating • Image quality • Speed
- 11. 4B-11 High-Quality Printers • Special purpose printers – Used by a print shop – Output is professional grade – Prints to a variety of surfaces
- 12. 4B-12 High-Quality Printers • Photo printers – Produces film quality pictures – Prints very slow – Prints a variety of sizes
- 13. 4B-13 High-Quality Printers • Thermal wax printers – Produces bold color output – Color generated by melting wax – Colors do not bleed – Operation costs are low – Output is slow
- 14. 4B-14 High-Quality Printers • Dye sublimation printers – Produces realistic output – Very high quality – Color is produced by evaporating ink – Operation costs are high – Output is very slow
- 15. 4B-15 High-Quality Printers • Plotters – Large high quality blueprints – Older models draw with pens – Operational costs are low – Output is very slow

Editor's Notes
- #5: Teaching Tip Figure 4B.5 on page 163 provides an excellent rendering of how the print head works. Be sure to refer to the image as you teach.
- #7: Insider information Nearly all of the electronics for the printer is kept in the ink cartridge. Thus, when the cartridge is replaced the printing components of the printer are replaced. Refilling cartridges is OK, but should not be reused more than 2-3 times.
- #9: Insider information The laser printer works on a similar process to a photocopier. The first photocopier as we know it today was invented in Astoria NY in 1938 by Chester Carlson and Otto Kornei.
