GRID LINES ON SPREADSHEET WON'T PRINT
I'm on a MacBook Pro OS X Yosemite 10.10.3 using Numbers to create a simple spreadsheet.
I want to print the grid lines on the spreadsheet. I have:
1) Clicked on Cell and chosen the type of border that looks like a + sign with a border around it, chosen the thin line.
2) I can see the grid lines on the spreadsheet on the screen, then I go to File>Print and I can still see the grid lines.
3) When I print there are no grid lines !!!
What am I doing wrong ???? I've spent the last hour and a half trying to figure this out.
Can somebody help please!
MacBook Pro, OS X Yosemite (10.10.3)
