Abstract
A customized font based on fixed font cells having certain non-printable pixels along its perimeter, and formed by a pixel grid having a higher dpi horizontal resolution as compared to its vertical resolution. By preventing any marking dots on adjacent pixels in a given row, a minimal amount of ink drops can be used to print digitized characters, and higher throughput is obtained by using a printhead having a nozzle pitch which is the same as the vertical print resolution, and which has a swath width which allows a complete row of character cells to be printed in a single pass of the printhead across the media.
