Could you share an image or more details around this question? I see that no one replied and I am guessing that others, like myself, are not sure of what the issue is you are describing here.
Please provide enough details to reproduce the issue or better yet - please provide a sample packaged workbook with steps to reproduce. Be sure to share Tableau version numbers as well.
Hi Patrick, I think he might be talking about captions, where if you print them from TD you have the option to include the caption, but if you print from server you only get the viz.
But this might also be a non 2018.3 thing because I can't find how to select the caption for printing like I used to do in older versions of Tableau - the print options panel that used to pop up.
