HP PCL Graphics Commands 9-37
The printer interprets the parameters as follows:
No parameters - Defaults to relative plotting mode for subsequent commands.
X, Y coordinates - Specifies 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.
Coordinates are interpreted in current units: as user-units when scaling is on; as plotter
units when scaling is off.
Pen Down (PD)
PD X , Y [ ... ;] or PD [ ; ]
This command lowers the printer’s “logical pen” and draws subsequent graphics
commands.

This command emulates a pen plotter that must lower the pen to draw lines on the page.
The printer interprets the parameters as follows:
No parameters - Prepares the printer to draw subsequent graphics commands.
X, Y coordinates - Draws (in current units) to the point specified. You can specify as many
X, Y coordinates as you want. When you include more than one coordinate pair, the printer
draws each point in the order given.
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.
Pen Up (PU)
PU X , Y [ ... ;] or PU [ ; ]
This command moves to subsequent points without drawing. Use the PU command to
move to another location without drawing a connecting line.
