1. An apparatus comprising:
- a memory configured to store a plurality of predetermined grids, wherein each location in the plurality of predetermined grids includes a pcode comprising a justification value and a pulse width value;
pcode circuitry configured to;
compare a predetermined pattern to a plurality of pixels in image data in order to examine image data; and
generate a command signal based on the comparison and select one of the plurality of predetermined grids from the memory to replace at least the plurality of pixels in the image data for printing,wherein the predetermined pattern corresponds to a risk of toner scattering, andwherein the toner scattering is caused by a lack of ventilation when toner is fused to paper.

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.

10. A method comprising:
-
storing a plurality of predetermined grids in a memory, wherein each location in the plurality of predetermined grids includes a pcode comprising a justification value and a pulse width value; comparing, with pcode circuitry, a toner condition pattern to a plurality of pixels in image data; generating, with the pcode circuitry, a command signal when the plurality of pixels matches the toner condition pattern; and outputting one of the plurality of predetermined grids to a laser based on the command signal, wherein the toner condition pattern corresponds to a risk of toner scattering or toner explosion and the toner scattering or toner explosion is caused by a lack of ventilation when toner is fused to paper. - View Dependent Claims (11, 12, 13, 14, 15, 16)
