Yeah. I resized in Inkscape… but probably need to go back and re-check and inspect further the HPGL itself. I had a quick look and it didn’t seem to have a unit of dimension, so my immediate thought was that the plotter is set to some scale (ie. mm vs. inch or somesuch)

The HPGL native plotter unit is 0.025mm.
You can set up user units with the SCALE command. There are several different ways of doing this, but you probably want
SC xmin,xfactor,ymin, yfactor , 2
Assuming that you have set up your inkscape plot in mm with a 0,0 origin. Insert after the IN; instruction -
SC0,40,0,40,2;
I haven’t tried this but this is taken from HP’s official HP-GL/2 Reference Guide
Thanks! That sounds just the ticket. I’ve got back to the space and am about to start investigating…
Belated reply: Inkscape sets the scale correctly in it’s export (it’s the funny DPI value, 25.4mm / 0.025 = 1016), but only exports correctly if the document size is the bounds of your drawing. I’ve updated the wiki page with all I learnt.
