ABSTRACT:
An apparatus and method of printing characters and symbols either vertically or horizontally on an elongated recording medium adjusts the position of vertically printed characters and symbols so that the vertically printed characters and symbols are evenly spaced on the recording medium. When a vertical printing is to be accomplished, dot pattern data in a data development buffer is rotated 90 degrees counterclockwise, and transferred to a vertical data development buffer. The rotated dot pattern data for each character is then moved in the longitudinal direction of the recording medium, as necessary, to ensure that each character will be positioned in the middle of its character pitch. The longitudinal adjustment ensures that the upper and the lower margin of each character are equal.
