Abstract: A printer for printing on both sides of a document, such as a check being printed at a point of sale terminal, uses a single printing station to print on both sides of the document. The document is moved along a document path and past the printing station, with the first side of the document being printed, with an end portion of the document then being positioned to extend through a slot within a rotor. The rotor is then turned through a 180-degree angle in a first direction, with an end portion of the document being held within the rotor and wrapped around a segment of the rotor. This end portion is next driven back to the printing station for the second side of the end portion to be printed upon.
