Cut-off lines

On the "FORMAT CELLS" box, the "Wrap Text" box is ticked on the
"Alignment" box and, on the "FORMAT" drop-down, I've clicked "AutoFit
Row Height" and "AutoFit Column Width".

On the screen, all cells display OK.

When I do PRINT or do PRINT PREVIEW:

-- the cells with one line prints/displays OK.

-- but when the cells have more than one line, the first line is OK
but the subsequent line(s) are cut-off.

How do I resolve this problem?

(I'm using MS Excel 2007)
