Abstract
A dot matrix printer has two print head carriages, supported in parallel, and two print heads for printing a receipt and a journal in a tandem printing station arrangement. A drive cam with a rail on the periphery thereof is coupled to both carriages to drive the carriages in opposite directions upon rotation of the drive cam. The movement of one carriage acts as a balance to movement of the other carriage and thereby eliminates or substantially reduces vibration during printing operation.
