Cell borders of a page expands to another page
I know that the title of my question isn't very good but I'll try to explain my problem ok!
I have some spreadsheets that I import form excel, and they are of the exactly size of a Letter page ok!
But I have a border in the external cells of this document, and when I print it the borders appears on the right side and bottom of the current page so numbers ask me to print not 1 but 3 pages.
I know that if I choose to print only the first page it will work, but sometimes I forget and it prints 3 pages that's a big waste of paper.
Does somebody knows how to fix or adjust this numbers behavior
