Send HPGL file to duplicate:

how many?    

Other versions:

x axis spacing
x axis offset     -     (view source)
x axis spacing + flip
x axis offset + flip

y axis spacing
y axis offset     -     (view source)
y axis spacing + flip
y axis offset + flip

The picture shows the terminology I'm using even though it's a mish-mash of several different types at once. Experimentation may prove a better teacher.

The two source examples are slightly outdated, but they are better examples and more straightforward than the current versions. They simply echo the HPGL to the browser.
