Hi Ian,
There is no way currently to control this - headers and footers are always placed halfway between the top/bottom of the page and the text - that is, halfway down the margins. The printable area does not affect PDF compile, but it does affect printing (this change was made because some users were finding the printer’s printable area to cause problems).
However, the good news is that for 3.0.3 I have added a couple of options:
- Confine to printable area (for printing only) - allows you to turn off printable area affecting things even for printing.
- Header Margin and Footer Margin - allows you to determine precisely how far up or down the the header or footer is from the top or bottom of the page (for print and PDF only). Leaving this as 0 results in the default behaviour of centring them.
So, this should give you the control you need. In the meantime, you can assume that the header and footer will fall roughly like this:
(Margin height - header/footer font height) / 2
(The font height isn’t always a reliable gauge, though, as the line height for text may be a few points higher than the font size.)
All the best,
Keith
