Summarizing comments is a convenient way to get a synopsis of all the comments associated with a PDF. When you summarize comments, you can either create a new PDF with comments that you can print, or you can print the summary directly. The summary is neither associated with nor linked to the PDF that the comments are derived from.

By default, Acrobat prints PDFs with any stamps that were applied. For the greatest control over how comments are printed, choose Comments > Print With Comments Summary.
