The other principal form of feeding paper into a dot-matrix or daisy-wheel printer is through a tractor feed, in which sprocketed wheels on either side of the printer fit into holes in the paper. As the wheels revolve, the paper is pulled through the printer.

Tractor-feed printers require special paper, whereas friction-feed printers can handle most types of cut-sheet paper, including envelopes. Many printers support both types of feeding mechanisms.
