I assume we're both using the latest MS Word.

On the Review tab, by the Tracked Changes icon, change "All Markup" to "Simple Markup." This turns on the Show Comments icon. To the left of this icon is the Delete icon with a small arrow under it. Click the arrow and select "Delete all comments in document." 

As for the editorial line by line changes, you should still be on the Review tab. To the right is the "Accept" option with a small arrow under it. Click the arrow and choose "Accept all changes and stop tracking."

Run the spell checker after all of these changes as an error (not likely spelling but maybe spacing) can creep in.

Then print.
