ABSTRACT:
A method and apparatus for conserving a substance dispensed by a printer engine for forming print on a media. As an example, the method stores a plurality of bits in a memory, the plurality of bits representing a cumulative pattern to be printed by reproducing the bits on the media. Each bit is either in a first memory state or a second memory state. The method further selects a subset of the plurality of bits, wherein the subset forms a first pattern and has a center bit. If each of the plurality of bits of the subset is in the first memory state, the method outputs to the printer engine a print bit corresponding to the center bit and in a print state which is opposite the memory state of the center bit. If, however, at least one of the plurality of bits of the subset is in the second memory state, the method outputs to the printer engine a print bit corresponding to the center bit and in a print state the same as the memory state of the center bit.
