Laser print apparatus that generates pulse width value and justification value based on pixels in a multi-bit image

A laser print apparatus comprising:

• a memory to store data defining an image including a plurality of pixels, each pixel of the image being represented by a multi-bit value;
• a first modulation code generator in communication with the memory to generate a pulse width value for each pixel in the image by appending a first portion of the multi-bit value for the each pixel to a second portion of the multi-bit value for the each pixel;
• a second modulation code generator in communication with the memory to generate a justification value for each pixel in the image based on the multi-bit values of pixels adjacent to the each pixel;
• and
• a laser print engine in communication with the first modulation code generator and the second modulation code generator to form an image on media based on the pulse width value and the justification value.

A laser print apparatus comprising:

• means for storing data defining a multi-bit image including a plurality of pixels, each pixel represented by an N-bit value, wherein N is greater than one;
• means for generating a pulse width value for each pixel in the multi-bit image by appending a first portion of the N-bit value for the each pixel to a second portion of the N-bit value for the each pixel;
• means for generating a justification value based on the values of pixels adjacent to the each pixel;
• and
• means for forming an output pixel on media based on the pulse width value and the justification value.

A laser print apparatus comprising:

• means for storing data defining a multi-bit image including a plurality of pixels, each pixel represented by an N-bit value, wherein N is greater than one;
• means for generating a pulse width value for each pixel in the multi-bit image by concatenating a most significant portion of the N-bit value for the each pixel to a least significant portion of the N-bit value for the each pixel;
• and
• means for forming an output pixel on media based on the pulse width value.
