ABSTRACT:
A non-impact printer apparatus includes a printhead having a plurality of recording elements. The printhead further includes a non-volatile memory that stores prebinned data representing recording characteristics relative to the recording elements. The prebinned data includes (a) data associating respective recording elements with respective bins; and (b) data relative to a characteristic of each bin. A controller means is located off of the printhead for generating tables for correcting for non-uniformity of the recording elements. The controller uses the prebinned data for generating the tables.
