Subject: Is there a way to fix a border of a table in a form to fit into one page A4-size paper when printing???
If you set the table to ‘fit with margins’ then it fits within the screen margins when on screen, then withing page margins when printing.
Alternatively you could experiment with fixed with tables to ensure that when printed they fit on an A4 sheet but this then depends on printer setting as if the user chooses to print out landscape or changes the print margins, it could mess it up.
