Group 5 Printers
Types of Printers
- Mainly print text and images by spraying ink droplets onto the paper
- Low cost, high-quality output, easy to use, pretty fast, quieter than dot-matrix
- Print head is less durable, expensive ink cartridges, not good for high volume
- Uses toner instead of ink.
- 3 major components
- Drum cartridge
- Rotating mirror
- toner cartridge and roller
- Thermal - A small portable printer
- 3D - A process of making a three-dimensional solid object virtually any shape from a digital model.
- Impact (almost entirely replaced by Non-impact)
- Dot Matrix
- A type of printer that produces characters and illustrations by striking pins against an ink ribbon to print closely spaced dots in the appropriate shape. Dot-matrix printers are relatively expensive and do not produce high-quality output. However, they can print to multi-page carbon copies, something laser and ink-jet printers cannot do.
- can print multi page carbon copies
- can print 50 to 500 characters per second
- print quality: Determined by the number of pins (the mechanisms that print the dots), it can vary from 9 to 24. The best dot-matrix printers (24 pins) can produce near letter-quality type, although you can still see a difference if you look closely.
- do not produce high-quality work
