>I have a file containing 2 pages. The second page is absolutely empty but I just cannot get ride of it. When I print, 2 pages (2nd is empty) will be printed out. I have tried to select a lot of rows below page 1, then right click, then select "delete". But the problem is still exist. Is it a bug?

I assume we are talking about Excel. Try deleting columns to the right of your last column of data. You most likely have a blank space in one of the cells. Next adjust your columns. I've seen problems where print preview did not match actual print outs. The solution was to shrink one of the cells by .01. htwh.
