The Export PDF option should include the actual changes that being made vs. just having the proof populate with the mark-ups (strikethroughs, boxes, etc.). We often work with agencies where we will have a point person in Workfront but then they turn the changes around to the actual creative team, and the print summary would be helpful for them to make that handoff because it would include the full extent of the changes that need to be made.
I know that to get around this you can either "Print to PDF" the print summary screen or share the proof to an email address, but it seems incomplete that the print summary doesn't show what the suggested changes are. I'm not sure what purpose it serves otherwise.
