S01484 METHOD AND APPARATUS FOR OPERATING A THERMAL PRINTER WITH UNIFORM HEAT DISTRIBUTION ABSTRACT OF THE DISCLOSURE A method and apparatus are provided for controlling a printer of the type having a number of blocks of print heads, each block including print heads preferably of the thermal print type. Data signals representing the selective energization of the print heads are stored, and these data signals are selectively read out to energize a group of print heads in each block, sequentially by block. After one group of print heads in each block is energized, another, different group of print heads in each block is energized, and so on, until all of the print heads have been energized. The print heads in each group are sufficiently spaced from each other to minimize thermal interference due to the energization of an adjacent print head. Consequently, the temperature of the print heads is distributed uniformly.
