An impact band printer for printing on either side of a print medium, such as paper 10, comprises a continuous flexible type band movable in front of a platen 12. As seen in Fig. 5, the type band 11 has alternate sets of engraved type characters 13 and 14 which are the reverse of each other and are arranged in a single row. In addition to timing marks 15 sensed by transducer 16, band 11 has check point marks 17 which are sensed by transducer 18 for indicating whether the forward or reverse set of type characters 13 and 14 is in position for impacting by the bank of print hammers 19.
