One possibility is that the printer itself is doing some kind of 
auto-emulation-sensing. My experience is that this kind of thing never 
works reliably when PostScript is involved.

1) Can you check the printer settings, to ensure its "personality" (or 
whatever it's called) is set to "PostScript" and not "auto"?
2) Failing that, what if you make sure the first line of your PostScript 
is always a comment beginning with "%!" or "%!PS-"?
