Abstract
An input/output device including a reading and a printing head of reciprocating shuttle type for reading and printing of images on respective first and second media. The reading head has reading portions spaced apart along the width of the first medium at a pitch greater than a desired reading pitch, while the printing head has printing portions spaced apart along the width of the second medium at a pitch greater than a desired printing pitch. The printing and reading heads are reciprocated as a unit along the width of the media to effect reading and printing with desired reading resolution and printing density, with the reading head pressed on the first medium, and with the printing portions pressed on the second medium. The input/output device comprises an actuator for selectively effecting either separation of the reading and printing heads from the first and second media, respectively, or pressed contact of the reading and printing heads with the media, respectively.
