A method some printers and plotters use to move PAPer by rotating one or both of a pair of spring-loaded rubber-coated rollers with the PAPer sandwiched between them. Friction feed printers are notorious for slipping when the rollers wear out, but can take standard typing PAPer. For printers with a sheet feeder, friction feed is more appropriate than sprocket feed which requires the holes in the PAPer to engage with the sprockets of the feed mechanism. (1997-07-09)
