Detailed explanation-1: -Dot matrix printers typically use a print head that moves back and forth or in an up-and-down motion on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper, much like the print mechanism on a typewriter or line printer.

Detailed explanation-2: -One of the most common kind of impact printers is a dot-matrix printer. It’s called an impact printer because we are literally taking a tiny pin inside of the print head, pushing it through a ribbon, and hitting a piece of paper to put a mark on that paper.

Detailed explanation-3: -A dot matrix printer is an impact printer that prints using a fixed number of pins or wires. Typically the pins or wires are arranged in one or several vertical columns. The pins strike an ink-coated ribbon and force contact between the ribbon and the paper, so that each pin makes a small dot on the paper.

Detailed explanation-4: -An impact printer forms characters and images on a piece of paper by hitting an ink ribbon mechanism that contacts the paper physically.
