USING  THE PM COMMAND

     
     The Polygon Mode ( PM ) command is used to define
     shapes, such as block letters or any unique area. After
     the shape has been defined, you need to exit polygon
     mode to fill and/or edge the polygon the is stored in
     the buffer.  For more information see the PCL 5 Printer
     Language Technical Reference Manual.

     SP1;                          Selects pen number 1,
                                   (black). Even though
                                   there is no physical pen,
                                   the SP command must be
                                   used to enable printing.
     
     PA2000,2000;                  Specifies absolute

                                   (3000,2000), and
                                   (3000,3000).

     PM1;                          Closes the first polygon.
     
     PD2080,2160,2480,2160,2480,
     2340,2080,2340,2080,2160;     Stores 5 locations for a
                                   subpolygon.
     
     PM1;                          Closes the subpolygon.
     
     PD2080,2660,2480,2660,2480,
     2840,2080,2840,2080,2660;     Stores 5 more locations
                                   for another subpolygon.
     
     PM1;                          Closes the second
                                   subpolygon.
     
     PD2920,2340,2920,2660,2720,
     2660;                         Begins a third subpolygon
                                   that draws the ground
                                   plug portion of the
                                   receptacle.
     
     AA2720,2500,180;PD2920,2340;  Stores a 180 degree arc
                                   that begins at
                                   (2720,2660), the previous
                                   current pen location, and
                                   ends at (2720,2500).
                                   Draws a line to
                                   2920,2340.
     
     PM2;FP;EP;                    Closes the subpolygon,
                                   and exits polygon mode.
                                   "FP" fills the polygon,
                                   using the even/odd
                                   default method, and "EP"
                                   edges the polygon and
                                   subpolygons currently
                                   stored in the buffer.
     
          NOTE:  The Even/Odd fill method of FP
                 is the default.  To determine
                 which portions of a single
                 polygon or a series of
                 subpolygons are filled when you
                 send a FP command, simply draw a
                 straight line extending from any
                 point within an enclosed area of
                 the polygon to a point outside
                 the polygon. FP fills the
                 enclosed area in question only
                 if the line you have drawn
                 intersects the edges of the
                 polygon an odd number of times.
                 For a visual example of this
                 please see page 21-15 of the
                 Updated PCL 5 Printer Language

     Ec%0A                         Enters the PCL mode.
     
     EcE                           Sends a reset to end the
                                   job and eject the page.
