Abstract
A printing apparatus for performing printing on a printing medium using a print head includes an electrical-power-distribution determination unit for determining a state of concurrence of respective control units for a sheet feeding mechanism, a sheet conveying mechanism, a carriage mechanism and the like and supplying optimum electric power at that time, even if a dedicated motor is provided for each of the mechanisms. For example, when the carriage mechanism is operating and the sheet conveying mechanism is performing driving, low-speed sheet feeding is performed. When neither the carriage mechanism nor the sheet conveying mechanism are performing driving, high-speed sheet feeding is performed. By thus optimizing distribution of electric power for a plurality of driving sources of the printing apparatus, high-speed recording with low electrical power can be realized.
