Impact printers are a type of printer that prints by striking an
inked ribbon against paper, similar to a typewriter. These
printers use mechanical components to transfer ink, making
them noisier than non-impact printers.

7. A dot matrix printer is an impact printer
that prints characters and images by
striking a series of tiny pins against an
inked ribbon to form dots on paper
Dot-matrix
Printers
IMPACT PRINTERS

8. Dot Matrix Printer
1. The printer has a print head with multiple pins
arranged in a grid.
2. These pins strike an inked ribbon, which
transfers ink onto the paper in the form of tiny
dots.
3. The combination of these dots forms
characters, numbers, or images.
4. The print head moves horizontally while the
paper moves vertically for continuous
printing.
