Abstract
A print control apparatus for a dot printer such as serial printer or line printer comprises a print head having a plurality of dot elements, a drive mechanism for driving the dot elements and a control circuit for controlling the drive mechanism, and energized by a limited capacity of power supply. The apparatus comprises a circuit for detecting a dot drive voltage based on a difference between an idling power supply voltage and a power supply voltage in a print mode and/or a circuit for detecting the dot drive voltage, based on print data supplied from a print data source. An effective print speed is changed in accordance with the detected dot drive voltage.
