HP 5961-0509 manual Example Using the Pen Down Command, 20-32The Vector Group

•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).
