The problem? Your users have more data than will fit within Excel's default margin settings. When they go to File | Print Preview, their suspicions are confirmed: Only five out of the six columns are visible.

To correct this by mouse, go to File | Print Preview. If you don't see dotted lines representing margin settings, click the Margins button to display them. Mouse over any of the margin lines. When the cursor changes to a bidirectional arrow, click and drag to change the margins visually.
In many cases, you can pull that last column back onto the page by shrinking the right and left margins. Save even more paper by shrinking the top and bottom margins, cutting a three-page print range down to two.
