Description
The LaserJet III was another significant breakthrough for HP. It was based on the same 8 ppm Canon SX engine as the LaserJet II. The LaserJet III offered two major improvements. It offered Resolution Enhancement Technology (RET). Although still a 300 dpi printer, RET allowed the laser to adjust the size and position of dots within a dot location in a character cell matrix and on the edges of graphics lines and arcs. This gave the printer an effective resolution of near 600 dots per inch, without requiring more memory or slowing down print speed.
