Abstract
A method of controlling operation of a print head to align imprints printed by the print head in two traverses in opposite directions is disclosed. The print head includes a row of printing elements that are operated selectively in a plurality of print cycles to print each imprint. Upon completion of printing a first imprint, signals corresponding to motion of the print head step the count of a counter. The stepping of the counter is terminated when the print head passes a reference position. During a reverse traverse of the print head, stepping of the counter is initiated when the print passes the reference position and operation of the print head to print a second imprint is initiated when the count reaches a predetermined count.
