A process for printing an image data signal, using a parallel input print head which has an input data bus which is narrower than the image data signal, includes the steps of splitting the image data signal into multiple data groups such that each data group (1) has a maximum allowable width equal to the width of the input data bus and (2) consists of consecutive binary value bits of the image data signal. The data groups are loaded to the print head, and the data of the one data group is printed according to its binary weighting in the image data signal. The loading and printing steps are repeated for each data group. The printing step comprises deamplifying the value of the bits of the data groups and amplifying a printer's output by a factor according to the binary weighting of each data group being printed.
