PO’s that have started printing too many pages. For example when printing a single page po, it will actually print 2 pages.
This is caused by the form fields slightly over lapping the edge of the page.
Simply edit each Tab (page 1 of 1, first of n, middle of n, last of n) and ensure that the fields do not overlap the edge of the white area of the grid.
And printing will work correctly again.
