Abstract

See full text

When a recording mode of a printer is changed to a resolution expansion mode when an internal temperature of a recording head falls or by an external indication, the number of divided blocks is changed so that the overlap of on time zones of block sub-division signals is prevented in order to assure that heaters of the recording head are energized for a sufficient time period. Thus, the heater energization time period for each block is extended without extending the total recording time.
