The printers can be classified into two categories which are as follows:
1. Impact printers In these types of printers, there is a mechanical contact between the paper and the printer head. These can further be classified as-Line printers (which can print a line at a time) and Daisy wheel printers (which can print a character at a time).
2. Non-impact printers In these types of printers, there is no mechanical contact between the paper and the printer head. The printing takes place with some electromagnetic thermal or laser techniques. The non-impact printers are more speedy and quieter than impact.
