A drum printer consists of a solid, cylindrical drum that has raised characters in bands on its surface. There are as many bands as there are printing positions. Each band contain all the possible characters. The drum rotates at a rapid speed. For each possible print position, that is, opposite to each band of the drum, there is a print hammer located behind the paper. These hammer strike the paper, along with the inked ribbon.
Typical speeds of drum printers are in range of 300 to 2000 lines per minute.
