working view v print view

Hi all, just trying to figure out how to work on my sheets (invoices) in the exact view that they will print. For example - I have a cell thats wrapped & when I enter in a description and its too long for the cell it fills to second line. thats all good and I can adjust row height to fit if necessary..... THE PROBLEM i'm having is that when I go to print preview the line that previously filled to the next line actually fits on the one line and prints on the 1 line too. I have been forever checking print previews to see if text fits or if adjustments need to be made prior to emailing out. SO how can i just use the active worksheet in the actual size it will print to avoid the time wastage.  hopefully this makes sense. C
