You may already realise, but in case not... Adobe Reader has an option 
to "Shrink oversized pages" when printing. You might not expect that to 
do anything when printing an A4 PDF printing onto A4 paper, but it 
actually shrinks the page slightly to allow for the non-printable 
margins around the page. To get a 1:1 scale print you have to select 
"Actual size". It remembers the last setting you use, so you have to 
remember to check what's it's set to each time.

Is the vertical offset incorrect on screen as well as when printed? When 
I first read that, I thought you meant it was wrong on-screen as well, 
but from your discussion below it sounds like the PDF is displayed with 
the correct margin, but prints with the wrong margin?

So if you have a PDF which displays on screen with the correct margin, 
but when printed it has the wrong margin? To get it to print with the 
correct margin, you have to produce a PDF which displays with an 
incorrect margin? Assuming you're printing the PDF at actual size, that 
would suggest the printer or its driver is in error (unless your PDF 
reader has the same issue as LibreOffice). Once LibreOffice has created 
a PDF, it has nothing to do with any difference between how the PDF 
reader displays and prints it.

If you open a PDF created from a completely different application, does 
that also print with different margins than when displayed on-screen?

Can you try printing your LibreOffice document and/or PDF on a different 
printer? Rather than wasting labels, you could of course print on plain 
paper and hold it up against the labels ;o)

How many Pentium designers does it take to screw in a light bulb?
1.99904274017, but that's close enough for non-technical people.
