The HPGL output has a few problems when imported into GC-Prevue (I don't
have a plotter) but the holes are there, as I expected.

You can download a demo, limited to 100 pins.

It's quite expensive to buy ($1000 upwards). EasyPC (same company but
different web site) is a lot cheaper, but less capable. It will also output
HPGL.
