#petermolnarfollowing the publish-in-pdf article, I decided to see if there's a simple way to pre-generate prints for my site and I found: https://weasyprint.org/ - this things is beautiful, it parses print CSS as well, except for srcset rules, sadly.
#petermolnarWhat I didn't realize is that I applied this to my category pages as well, so now I have a certain 35MB file with 425 pages (!) for the whole of my photo category page.
