Abstract

This invention relates to a method for aligning or staggering the rows of wires in a print head so that throughput speeds are increased. Throughput speed is an important performance characteristic in both high speed draft and near letter quality one-pass printing in wire matrix printers. These wire matrix printers include, but are not limited to, configurations that have their respective wire ends arranged in two or more columns, such as an eighteen or twenty-four wire print head. (Image Omitted) A horizontal cross-section of an eighteen wire print head structure 1 is shown in Fig. 1 and comprises a U-shaped cavity 2 extending from within the print head structure 1 to outside the bottom portion. The U-shaped cavity 2 has disposed at its bottom a left column of nine print wires 3 and a right column of nine print wires 4.
