A liquid ink printer in which liquid ink is deposited on a recording medium in swaths in response to image data received thereby including a power supply, having a maximum power rating determined as a function of a number of passes per swath necessary to compete a swath having maximum ink coverage. The printer includes a print power regulation circuit, including a regulation circuit input, for receiving the image data, and a regulation circuit output, for transmitting image data in a number of passes per swath, the number of passes per swath being determined as a function of the maximum power rating, and a liquid ink printhead, coupled to the power supply and to the print power regulation circuit, for ejecting the liquid ink according to the transmitted image data. A printer driver, which can include the print power regulation circuit, determines the amount of ink coverage to complete a received swath of information and in response thereto determines the number of passes necessary to complete the printing of the swath. The power rating of the controlled according to the number of passes per swath and provides for an optimized power supply.
