Correct Answer is: Drum printers
A drum printer is a type of line printer that uses a rotating drum to transfer an image onto paper. The drum contains a full character set for each printing position. The drum rotates to position the characters.
Drum printers are a type of impact printer that works by striking an inked ribbon against the paper. They are fast and reliable, and produce high quality printed output. However, they are slower and print in a lower resolution than laser printers.
