Hello Hartric
I want to create a doc that can be printed in landscape with marks to show
fold lines for a triple fold along the longest side
.... and the problem is ...?
Not sure what exactly you mean in the "Subject" line with "... but
printing in portrate".
Is this going to be a document longer than page/two pages double-sided?
You probably have to calculate the position of your fold lines yourself.
Then insert them, say, as a line (Drawing object) anchored to a header
or footer area.
