Accept the changes. (You don't say which version of Word, and there were big
differences between 2000 and 2002, so you'll need to check Help on your own
system for more details.)
Alternatively, if you want to retain the tracked changes in the file, but
not show them with the vertical line in the print, you'll need to change the
way changes are displayed. Again, big differences between versions - in 2002
you can just choose 'Final' view, or change the mark-up options.
