The minimum bottom margin for pdf24 is 1.9cm. If the margin is set to less then there is a warning when creating pdf. But there is no warning if the footer extends down into the bottom margin. Since it is normal for footers to be in the zone which is cut off by pdf24 then it appears that pdf24 is inappropriate for documents with footers.
Similarly if the page is landscape the bottom margin is min 1.07cm (and the right margin min 1.9cm) although left and top margins can be less.
Why? Does the programme need fixing or is there a setting I have missed?
