Abstract:
A printing apparatus for printing to a printing medium by moving a print head orthogonally to a direction in which the printing medium is transported along a transportation path to a printing unit, said printing apparatus comprising:a transportation roller pair selectively moveable between an open position and a closed position in which the transportation roller pair holds and transports the printing medium to the printing unit; and a driver to move the transportation roller pair; a receiver to receive commands from a host device for controlling the operation of the printing apparatus; and a controller responsive to a print head moving command; wherein the controller is adapted to cause, in response to each print head moving command, the driver to bring the transportation roller pair to the closed position prior to causing the print head to move, such that the transportation roller pair is always closed when the print head moves, and such that the print head moves after the transportation roller pair is closed to hold the printing medium but before the printing medium is advanced.
