HP PCL/PJL reference (PCL 5 Printer Language) - Technical Reference Manual Part II

• Coordinates are interpreted in current units: as user-units
when scaling is on; as plotter units when scaling is off.
• Whether the PD command uses coordinates or increments
depends on the most recently executed PA or PR command.
If no PA or PR command is issued, absolute plotting (PA)
is used.
• When you use the symbol mode (SM) command, PD draws
the specified symbol at each X,Y coordinate. When you use
the polygon mode (PM) command, the X,Y coordinates enter
the polygon buffer (and are used when the polygon is edged
or filled).
