I'm phenominally late to this party, but you are aware that Acrobat's default behaviour is "shrink to fit"? Turn that off and you should be in business (albeit missing some stuff at the sides if your pcb's really big, but that would be asking for trouble).
Being a snob, I don't totally trust windows for accurate printing, but between them Adobe and HP should have it all working nicely.
