A workpiece carrier positioning structure used in an auto printing and drying machine for controlling positioning of a workpiece carrier fixedly carried on a carriage sliding in a track, for enabling the workpiece carrier to be positively maintained in a printing/drying position, in which the workpiece carrier is transversely slidably mounted on transverse axles at the carriage and supported between compression springs on the transverse axles, and a longitudinal slide is controlled by an air cylinder to move a notched stop block into engagement with a roller at the bottom side of the workpiece carrier to hold the workpiece carrier in the printing/drying position when the carriage approached.
