randomly does/doesn't print full page
 

The print area is set and in print preview the entire page shows, however
when it prints it sometimes doesn't print the last few lines. Sometimes it
will even print half the line (as in top half). I have checked the page
breaks, margins... am confused. I print repeatedly and get approx. 1/2
correct and 1/2 missing last few lines - with no changes in page. It is very
erradic. I know it can't be a printer problem b/c I don't have this problem
in other programs - word, adobe...
