+# Printing a PDF as-is
+
+The PDF `margin-test.pdf` is A4 sized, with top and bottom margins of 15.3mm.  You can see the Ruby code which generated it in `pdfer.rb`.
+
+I need to print this PDF as-is on A4 paper.  It has to be as-is because I'm printing sticky labels and they need to align.
+
+When I view the PDF on screen (in Preview) at 100%, it displays correctly.  I can measure the margins and verify they are correct.
+
+But when I print it the box is not centred vertically: the top margin differs from the bottom margin.  I have fiddled with the scale settings in the print dialog but to no avail.
+
+It must be possible to print at 100%...can anyone enlighten me?
+
+Thanks,
+
