Detailed explanation-1: -Well this is possible because they are impact printers. You can add multiple sheets in dot matrix printers with a carbon paper inserted between subsequent sheets. And then by the virtue of impact printing, the same dots will get printed on the other pages. Dot matrix printers allow for as many as 10 copies at a time.
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: -It is a type of printer that works by direct contact of an ink ribbon with paper. These printers are typically loud but remain in use today because of their unique ability to function with multipart forms.
Detailed explanation-4: -The main reason why people still buy dot-matrix printers is that because they use an impact technology they can be used with multipart forms. The pressure of the needle against the ribbon is transferred through the top copy to the carbon paper or carbonless paper beneath it.
Detailed explanation-5: -Essentially, a thermal printer prints by burning the paper. Because of this, they don’t have very many moving parts compared to their counterparts and can print much faster. Impact printers, also known as dot matrix printers, work by using small dots to impress an ink ribbon into the paper.
