Impact Printers.
carbonised ribbon is essential part of
A dot matrix printer or impact printer is a type of computer printer and prints by impact, striking an inked cloth or Mylar ribbon against the paper.
A dotmatrix printer uses a ribbon and pins to transfer Inc. onto paper. This type of printer is no longer made and very few are still in use.
No, a dot matrix printer has small pins that hit a ribbon of ink. A laser printer uses toner type ink.

A impact printer uses a head or a needle on a ink ribbon to make a mark on the paper. Like dot matrix printers and daisy wheel printers.
A band printer is a line printer that uses a metal band, or loop, of type characters as its printing mechanism.
A band printer is a line printer that uses a metal band, or loop, of type characters as its printing mechanism.
The difference is the technology used in the printing. The dot matrix printer uses a matrix of needles that press through an inked ribbon to leave marks on the paper. The laser printer uses a roller system to leave charged area on the paper which attracts toner (fine particles of pigment) to stick to the paper. The dot matrix printer is largely obsolete nowadays; it has been replaced by laser/ink jet and thermal systems which are much quieter - making them more suitable for office and home use.
Several types of printers used an ink or carbon ribbon in the way you described. The daisy wheel printer and ball printer would spin a wheel that has the printable characters, then the wheel would strike the ribbon, leaving an imprint on the paper. The dot matrix printer used a number of pins that struck the ribbon to generate a printable character. The chain printer had several full sets of all printable characters on a long chain, and the chain spun rapidly on a track. As the appropriate printable character arrived at the proper location, a high speed solenoid driven hammer struck the chain, causing the ribbon to leave an imprint on the paper.
