A paper transport device in printers (1), particularly in dot matrix printers, for the feeding of continuous webs (6) by transversely displaceable tractors (7, 8) which are arranged in pairs on the printer frame. The tractor pins (9) engage into the edge perforations of the continuous web (6) and the pin belts (10) are guided over at least one wheel (11) of the tractor (7, 8) and at least one driven tractor wheel (13) is present. The device is equipped with a locking device so that the tractor (7, 8) operating as push means or as pull means is mounted in each case on a drive shaft (14) and in each case prevented from turning on the printer fram (1a) by a projection (16) on the side (15a) opposite the drive shaft (14) or by a swingable tractor flap (24).
