Abstract
A method and apparatus for processing a plurality of bits stored in a memory, where the plurality of bits represent a cumulative pattern to be printed by reproducing the stored bits in a fast scan direction. Each bit stored in memory has a state (e.g., binary 0 or 1). As an example, the method selects a first subset of the plurality of bits, wherein the first subset forms a first pattern and has a center bit. Further, the method selects a second subset of the plurality of bits, wherein the second subset forms a second pattern and has a center bit coextensive with the center bit of the first subset. Next, the method determines, based on the states of the bits of the first pattern, whether the state of the center bit should be printed in the same state as it is stored in the memory. In addition, the method determines, based on the states of the bits of the second pattern, whether the state of the center bit should be printed in the same state as it is stored in the memory.
