pistekirjoitusvälineet

Pistekirjoitusvälineet, also known as dot matrix printers, are a type of impact printer that creates fully formed characters by striking a matrix of wires against an inked ribbon to form characters on paper. These printers were popular in the 1980s and 1990s due to their relatively low cost and ability to produce high-quality text and graphics. They are known for their distinctive sound, which is caused by the striking of the print head against the ribbon.

Dot matrix printers come in two main types: 9-pin and 24-pin. The 9-pin printers use a 9-wire matrix to form characters, while the 24-pin printers use a 24-wire matrix. The 24-pin printers produce higher quality text and graphics than the 9-pin printers, but they are also more expensive.

Dot matrix printers are still used in some specialized applications today, such as in the printing of receipts and labels. They are also used in some industrial applications, such as in the printing of barcodes and other machine-readable codes. However, they have largely been replaced by inkjet and laser printers in most office and home environments.
