PR, Plot Relative

This command establishes relative plotting and moves the pen to specified points, with each move relative to the current pen location.

*PR and PE have extended ranges of -230to 230 - 1 plotter units. If the current pen position goes out of this range,the printer ignores HP-GL/2 commands until it receives an absolute PA or PE coordinate within the extended range.

The printer interprets the parameters as follows:

zNo Parameters — Defaults to relative plotting mode for subsequent commands.

zX, Y (Increments) — Specify incremental moves relative to the current pen location. When you include more than one relative coordinate pair, the pen moves to each point in the order given (relative to the previous point), using the current pen up/down status. If the pen is up, PR moves the pen to the point; if the pen is down, PR draws a line to the point. Lines are drawn using the current line width, type, and attributes.

•When you use the symbol mode (SM) command, PR 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).

•Coordinates are interpreted in current units: as user-units when scaling is on; as plotter units when scaling is off.
