There are also display options for the markup that is currently present in your documents. You can show so-called balloons with markup. You can also decide how changes should display in the main body of the document. These options are specific to your Office installation and they do not travel with the document.
Balloons with markup
Use the Display for Review drop down to decide what you want shown in balloons in the Markup area on the right hand side of the Word window. You will find the drop down in the Tracking group on the Review tab. The main distinction is between showing markup in the so-called balloons (that is, in the Markup area) and showing the markup inline in the document. There is a third option to show formatting, only, in balloons. (In the screen shot shown below, that option also affects comments but this is because I am displaying comments in the classic way, and not the modern comments.)
If you choose not to display markup balloons, they won't print, either.
Note that comments usually print in balloons regardless of these settings. This applies to the modern comments in Word (no to classic comments).

Inline formatting of markup
Finally, you can use the Advanced Track Changes Options dialog box to decide how insertions and deletions should display and print.
