Send the Printer an HP-IB Command
You will need to send the printer an IP command to specify a specific
rectangular region on the paper. This is done by sending the printer the
IP HP-GL command.
The IP command specifies the size and the position of the printed image
on the paper. The units are thousandths of an inch, so 8500 units would
be 8.5 inches. The arguments to the IP command are
IP LowerLeftX,LowerLeftY,UpperRightX,UpperRightY;
The paper is numbered as shown in Figure 8-1.
Figure 8-1 Paper Numbering
Typically, a margin around the image of 0.5 to 1.0 inches (500 to
1000 units) is used.
TIP When performing hardcopies of the measurement graph only (excluding
the marker table), the hardcopy image looks best with an aspect ratio of
approximately 1.3:1 (x:y).
