This is a character printer. In which there is a print head which rotates back and forth and up and down. It prints by hitting on the inked ribbon. It comes in two types of capacities, 80 column and 132 column. In this, the printing cost is less than other printers, but the quality and speed of print is less than other printers.

In this, only one color can be printed at a time, hence it is also called mono printer. Its capacity is measured in DPI (Dots Per Inch).

(ii) Daisy wheel printer:
