Non-impact printers use different methods to place ink (or another substance) on the page. Slide 5: Overview of Printers - Evaluating Printers When evaluating printers, consider four criteria: Image quality – Measured in dots per inch (dpi). Most printers produce 300 – 600 dpi. Speed – Measured in pages per minute (ppm) or characters per second (cps). Initial cost – Consumer printers cost $250 or less, but professional printers can cost thousands of dollars. Cost of operation – This refers to the cost of supplies used by the printer. Slide 6: Dot Matrix Printers How Do Dot Matrix Printers Work? Performance Slide 7: Dot Matrix Printers - How Do Dot Matrix Printers Work? Dot matrix printers are a common type of impact printer. A dot matrix printer's print head contains a cluster of pins. The printer can push the pins out to form patterns in rapid sequence. The pins press an inked ribbon against the paper, creating an image. Slide 9: Dot Matrix Printers - Performance Lower-resolution dot matrix printers use nine pins. Higher-resolution models have 24 pins. Speed is measured in characters per second (cps). Some dot matrix printers print 500 cps. Slide 10: Ink Jet Printers How Do Ink Jet Printers Work? Performance Slide 11: Ink Jet Printers – How Do Ink Jet Printers Work? Ink jet printers are an example of non-impact printers. The printer sprays tiny droplets of ink onto the paper. Ink jet printers are available for color and black-and-white printing. Slide 13: Ink Jet Printers - Performance Ink jet printers offer speeds of (2 – 4 pages per minute ppm) and resolution (300 – 600 dots per inch dpi), comparable to low-end laser printers. Ink jet printers are inexpensive and have low operating costs. Slide 14: Laser Printers How Do Laser Printers Work? Performance Slide 15: Laser Slide 16: Laser Printers – How Do Laser Printers Work? Laser printers are non-impact printers. They use heat and pressure to bond particles of toner to paper. Laser printers are available for color and black-and-white printing. Slide 18: Laser Printers - Performance Laser printers provide resolutions from 300 – 1200 dpi and higher. Black-and-white laser printers usually produce 4 – 16 ppm. Laser printers produce higher-quality print than ink jet printers, but are more expensive. Slide 19: Snapshot Printers Snapshot printers are specialized, small-format printers that print digital photographs. Snapshot printers are fairly slow, and can be more expensive to operate Slide 20: Snapshot printers are popular among digital camera users Slide 21: Other High-Quality Printers Print shops and publishers use these printers to create high-quality color images: Thermal-wax Dye-sublimation Fiery IRIS Plotters Slide 22: Inkjet Plotter Plotters use mechanical, ink jet, or thermal technology to create large-format images for architectural or engineering uses. Slide 23: lesson 6 Review List the three most commonly used types of printers. List the four criteria you should consider when evaluating printers. Describe how a dot matrix printer creates an image on a page. Explain the process by which a laser printer operates. List five types of high-quality printing devices commonly used in business.
