Abstract

A method and apparatus for printing data on a print medium is disclosed. The apparatus is configured to format print data to pixel data, the pixel data including pixel values; identify a grid of pixels having a predetermined pattern of pixel values; obtain predetermined pcode grid from memory for the identified grid of pixels; and send the predetermined pcode grid to controller circuit for printing.

Claims

1. An apparatus comprising:

a first processor, the first processor adapted to;

identify a grid of pixels having a predetermined pattern of pixel values, the predetermined pattern optimized to minimize scattering of toner on a media caused by ventilation of gas and water vapor;

if the grid of pixels having the predetermined pattern is identified, obtain a predetermined pcode grid from a memory, the predetermined pcode grid corresponding to the identified grid of pixels; and

send the predetermined pcode grid to a controller circuit for printing in place of the grid of pixels.
