Answer : 3. "dot matrix printer "
Explanation :
Dot matrix printers use printer ribbons. A dot matrix printer is a type of impact printer that produces characters and images on paper by striking a series of dots against an ink-soaked ribbon. The ribbon transfers ink onto the paper to create text and graphics. Dot matrix printers were widely used in the past for tasks such as printing invoices, receipts, and multipart forms.
