Abstract

Several raster-scan dot matrix impact printers are currently available. One type of printer uses the technique of a one-piece reciprocating "column" of print fingers and a bank of high current hammers to strike the fingers. Another type of raster-scan printer uses sets of replaceable fingers on a reciprocating assembly consisting of fingers and hammers. In both types, each finger prints several character positions. This arrangement is largely necessitated by the width of the hammer assembly required to drive the print fingers.
