Using Hardcopy Features to Print or Plot Results
Example IP command
For example, to print a hardcopy image on the top of a portrait A-size
sheet of paper, you can use about 7.5 inches of the paper's 8.5 inch width.
The width of the image would be 7500 units, beginning at the left margin
of 500 units and ending at the right margin of 8000 units. Using an
aspect ratio of 1.3:1, the height should be 7500 / 1.3 = 5769. The top
margin of the paper is at 10000, so the bottom of the image should be at
10000 − 5769 = 4231. Plugging these numbers into the HP-GL IP
command gives:
IP 500,4231,8000,10000;
Using the same calculations for an A-size sheet of paper in landscape
orientation gives:
IP 500,7,10500,7700;
The numbers shown in these examples were developed using an
HP LaserJet 4. Other printer’s margins may vary slightly.
Perform a hardcopy dump HP-GL format
Once your printer is set to accept HP-GL commands, you can perform a
hardcopy using the SCPI HCOP;*WAI command.
