A data printer wherein a slip is dropped in a guide chute and a serially operable print head is moved along the length of the slip to print a line of characters. A line feed device comprises a drive gear meshing with a driven gear carrying a feed roller for frictionally advancing the slip from one print line position, extending parallel to the length of the slip, to the next. The driven gear is moveable about the axis of the drive gear and is forced into frictional engagement with the slip by the rotational force imparted to the driven gear by the drive gear.
