This printer works like a typewriter. A print head travels back and forth along a bar. The head has a number of pins that can pop out to strike the paper through an inked ribbon. Typical numbers of pins are 9 and 24. This printer has the lowest print resolution and hence it yields the lowest print quality. It is the slowest and it works through strikes (impacts), so it has the highest noise level. However it is the cheapest. Also, it the most suitable for printing on multicopy forms that rely on impact to transfer printed characters from one copy to the next. It is also most suitable for printing on continuous perforated papers. |
