Claim:
1. A method for printing pixels in an image comprising: identifying, with a controller, a first pixel in multi-bit halftoned image data stored in a memory to be printed by an inoperable inkjet in a plurality of inkjets; identifying, with the controller, a plurality of neighboring pixels in a predetermined region around the identified first pixel, the pixels in the identified plurality of pixels having multi-bit values corresponding to deactivated pixels; identifying, with the controller, at least one neighboring pixel in the predetermined region of pixels around the identified first pixel to compensate for the identified first pixel with reference to a search of the predetermined region of pixels; generating, with the controller a modified multi-bit halftoned value for the identified at least one neighboring pixel to control operation of a neighboring inkjet of the inoperable inkjet to eject an ink drop based on the modified multi-bit halftoned value for the identified at least one neighboring pixel; and storing with the controller the modified multi-bit halftoned value for the identified at least one neighboring pixel in the memory to control operation of the plurality of inkjets to produce a printed image with the plurality of inkjets other than the inoperable inkjet to compensate for the inoperable inkjet.
