ABSTRACT:
Thermal printing apparatus is operable for applying images to opposite first and second sides of a continuous strip. The apparatus includes first, second, third and fourth thermal printing assemblies actuatable for applying first, second, third and fourth images to the continuous strip at first, second, third and fourth printing stations. The first and third thermal printing assemblies are mounted on reversible mounting assemblies capable of mounting the respective thermal printing assembly in a first position wherein the printing assembly is actuable for applying an image to a first side of the strip, and a second position wherein the printing assembly is actuable for applying an image to a second side of the strip. The apparatus further includes a drive assembly including a rotatable drive roller for longitudinally advancing said strip so that passes through the printing assemblies, a stepping motor rotatable at a predetermined fixed rate of stepped rotational increments per revolution for rotating the drive roller to advance said strip, and a controller responsive to a predetermined number of stepped rotational increments of the stepping motor corresponding to a predetermined distance between the printing assemblies for actuating the printing assemblies to apply images to the first and second sides of the strip.
