Information on Impact Printers
There are many different types of printers on the market and the computer printer itself has gone through a complex transformation since its inception. Impact printers are one of the oldest types and can still be found in use some places today.

Identification
-
An impact printer uses a head or a needle coated in ink to apply pressure on a piece of paper in enough places to create an image of the letters, words and phrases sent to it from a computer.
Types
-
These printers include various models. Dot-matrix printers work by striking a pin against an ink strip and a piece of paper to create a series of dots that make up an image. A daisy wheel printer, on the other hand, has a disk covered in raised letters, which spins and applies the correct letters, one at a time.
-
Resolution
-
Dot-matrix printers can achieve varying resolutions based on the number of pins found in a print-head. These range from about nine to 24, with 24-pin print-heads creating a much higher resolution.
Considerations
-
Impact printers have been replaced, for the most part, by laser and inkjet printers, which offer increased speed, efficiency and resolution.
