You're on the right track, this is because your report is too wide. You have to verify three things to get printing to work: page size, margins and the width of the Body.
Go to the drop-down at the top of the Properties window and choose Body. The Size will tell you how how large your working area is, and the width is constrained by the position and size of the fields in your report. The Body width + Left margin + Right margin determines how wide the page is, and you're likely over 8.5.
