For what it's worth, I also struggled with this problem when generating 
labels from a web page.  They print perfectly on my own printer, but 
were offset in Y on other printers.  I finally had to break down and add 
an "Enter top margin:" option.  I had people send me a sample printout, 
and I would tell them what value to use.  They just had to remember to 
do it the same way every time.

I suppose if I were a real man, I would have stored it in a cookie...
