There are many types of printers available. However, all printers fall into two basic categories: impact and non-impact printers. Non-impact printers give both higher print quality and faster printing speed than impact printers. Because of this, non-impact printers are popular with both professionals and consumers.
Function
On an impact printer, the print head comes in direct contact with the paper. On a non-impact printer, the type is formed without the print head coming into direct physical contact with the paper.
Types
Types of non-impact printers include: ink-jet, bubble-jet, laser and thermal printers.
Benefits
Non-impact printers offer better print quality, faster printing and the ability to create prints that contain sophisticated graphics, such as photographs.
Technology
Non-impact printers use either solid or liquid cartridge-based ink. This ink is either sprayed, dripped or electrostatically drawn onto the page.
Maintenance
Non-impact printers typically require little maintenance beyond replacing the print or toner cartridges.
Considerations
When choosing a non-impact printer, take into consideration how you will be using it. Ink-jet printers offer a nice compromise between print quality and price. If speed and quality are more important than cost, you might need a laser printer. Laser printers are available in black and white or color (used for graphics).
