  • Page 19: Line Matrix Printing

    Line Matrix Printing Your printer is an impact printer; it creates characters by printing ink dots on paper. The dots are printed on an invisible matrix mapped in printer memory. (See Figure 1–2.) Dot impressions are made by an array of steel hammers mounted on a rapidly oscillating shuttle.
  • Page 20 During each sweep of the shuttle, the hammers print dots at the required positions in the dot row. When the shuttle reaches the end of a sweep, it reverses direction, the paper is advanced one dot row, and the hammers print the next row of dots as the shuttle sweeps in the opposite direction.
  • Page 21: Printing Speed

    Printing Speed The speed at which text prints is measured in lines per minute (lpm). This speed is inversely proportional to the number of dot rows required to produce a character line, regardless of the number of characters in the line. More dot rows are required to print lowercase characters with descenders;...
