         The default line width is 0.35 mm. nWidth is in 100th's of mm, so 1
         is 0.01 mm. The HPGL command issued is a PW and only works with the
         LaserJet III in HPGL mode.

         Each pen in the plotter can be assigned to one of the 16 colors.

         Each color, 0 to 15, can be translated to a shade for solid fills.
         nShade ranges between 0% and 100% where 0% is no shading and 100% is
         solid black.
