sprocket feed

printer (Or "tractor feed", "pin feed") A method some

printers use to move paper by rotating wheels with pins or

studs (tractors) that engage holes along the sides of the

(usually fanfold) paper. A sprocket feed printer does not

slip unless the paper jams, but cannot feed standard typing

paper or work with a sheet feeder like friction feed.

Some paper for sprocket feed printers has the edge strips with

the holes in detachable from the rest of the paper. These

strips are known as chad (and other names).
