Abstract
A printing machine wherein printing onto a substrate is effected by a first movement of a print head (1) downwardly into contact with the substrate and then by a second movement over the surface of the substrate while thermal printing elements within the print head (1) are selectively energized. The first movement is controlled by downward movement of a pair of rollers (6,7) operated by synchronized angular movement of a pair of eccentric shafts (8,9) one of which is freely mounted within each roller (6,7). The first and second movements are driven by a first and second stepper motor respectively. The rollers may be coupled by drive belts (4,5).
