That’s exactly why the 30 second timeout limit ends up with wasting resources rather than saving them: it forces me to spin the renderer many times instead of just once.
The app can usually make an estimated guess about the time required to render each form. So the “5 at a time” chunking could be dynamically set.
Thank you for taking the time to play with it!
Right now I have other priorities and can’t spend time on that app. Last week a colleague needed to print a PDF that was hitting the limit. I started debugging the app, and after a few attempts, one “accidentally” completed the rendering on time. I sent that PDF to my colleague and put this problem in my todo list. I’m sure soon there will be another large truck carrying a lot of stuff, and printing its packing list will take too long, and I will have a look at your solution, and maybe add a clone link to show my version.
