I think I might have figured this out for you. At the beginning of just about every .plt file, before the HPGL code starts, there are usually a whole string of ESC sequence codes used to tell the plotter to wake the hell up, use hardware or software flow control etc, and set up a bunch of other parameters before starting on the plot data. These codes are sometimes very plotter specific. That's is why I used the .hpgl extension; the file I generated contains only HPGL code and no plotter specific control codes.
HOWEVER, it is very possible that the fools who designed the engraver software your friend uses intended for it to emulate a specific model of plotter. As such, it expects to see the ESC control codes specific to that emulated plotter at the beginning of every .plt file your send it. If it doesn't get them, it rejects the plot file as being for the "Wrong HP-GL plotter version", even though it contains valid HPGL data.
Again, try examining a .plt file that actually works. See if there are any ESC characters and other junk in it before the actual HPGL code starts. If there are, try copying them into the begining of the HPGL file I sent you.
Also, were you trying to engrave directly off the HPGL file I generated? That probably won't work because it is scaled for a letter sized sheet of paper. The data in it will need to be scaled and rotated to fit on your zippo before it can be engraved.
