0= grid intersection; device draws pixels centered at grid intersections (see Figure 2-1).

1= grid centered; device draws pixels centered inside the boxes created by the grid (see Figure 2-1).

The command is the HP-GL/2 version of the PCL Pixel

Placement command. Whatever mode is selected, using the

HP-GL/2 PP command also applies to PCL operation.

Likewise the PCL Pixel Placement command also affects

HP-GL/2 pixel placement.

Notes Microsoft Windows fills polygons based on grid centered method.

This command determines how pixels will be placed for both HP-GL/2 and PCL operation.

The PP command is not defaulted by an IN command.
