Abstract:
1. A thermal printing method comprising: moving a first portion of a substrate to be printed in a first direction past a thermal print head; printing the first portion of the substrate passing the thermal print head in the first direction with a first sub-block of data of a block of data during a first printing act; interrupting the printing of the substrate by the thermal print head following printing of the first sub-block of data and reversing the direction of movement of the substrate such that a back distance section of the first portion of the substrate passes the thermal print head in a second direction opposite to the first direction; moving a second portion of the substrate that includes the back distance section in the first direction past the thermal print head such that the back distance section of the substrate again passes the thermal print head in the first direction; and printing the second portion of the substrate passing the thermal print head in the first direction with a second sub-block of data during a second printing act, the portion of the second sub-block of data printed on the back distance section of the substrate during the second printing act corresponding to the data printed on the back distance section of the substrate during the first printing act.
