Abstract

This article describes a technique useful in any high speed printer where mismatch between the possible carrier positions and desired head print positions exists. In this particular design, the carrier moves only in multiples of 1/15", but on the fly printing can be done anywhere within 1/240" boundaries. The technique enables the use of one set of formulas for both right to left and left to right directions of carrier travel, thereby decreasing the amount of storage space required for the code. "Adjust up" means moving the head position to the next multiple of 1/15". "Adjust down" means moving the head position to the previous multiple of 1/15". No adjustment is required if the desired head position is on a 1/15" multiple. If Print Left to Right, then Fold Adjust = 0 (Image Omitted)
