Oh, got it. I'm just going to restate what you want for my own benefit: you
have a worksheet with text in some places and blank in others, but you want
the grid lines to stay there, even if there's no text in them. Got it.
Okay, are the empty cells formatted to actually have grid lines (not the
default gray lines that don't print)? Highlight the cells you want to have
the grid lines, then Format> Cells> Border. Make sure you choose visible
lines (like black) and apply them. I'm guessing you've already done this,
right? Well, it won't print all of those lines there unless you put something
in a box at the bottom right. Make the print lines visible so that you can
see which box is the bottom right. Put a space in that box. Now, print
preview. That should make the whole page have the gridlines, even the boxes
without text.
