Printing is working
It was a painful process with lots of trial and error and wasted trees, but SlideMagic 2.0 beta users can print their presentations as of v2.19 without using the PDF conversion bypass. I am still working on improving the resolution without maxing out on memory, and fixing small formatting issues (exact centering of the slides), but the basics are there.
For those who are interested. In the beginning of my coding project I was cursing this parallel processing of lines of codes, no I actually start using it to my advantage by speeding things up. PowerPoint and PDF conversion will soon move to a background process.
