Hi Jim, Print proof comments was designed this way (printing only pages that have a comment/markup). We are currently looking at re-working print summary solution. I will pass your feedback regarding possibility of printing all proof pages to the appropriate team - they will investigate if we are not limited by a browser that loads pages - considering scenarios of proofs with multiple pages (hundreds). Another way of generating PDF for the whole proof pages is using PDF option
