Not sure why you’re testing with the Windows-specific Microsoft Print to PDF printer driver when your goal is to run the program under Wine? Even if you get it to work under Windows, how would that possibly help you when you run Sumatra under Wine?
My advice would be to actually do your testing under Wine itself, with a Linux pdf printer driver such as cups-pdf. Also, if you get it to work then do let us know!
I am even more intrigued why you would even atempt to use SumatraPDF to convert to an image only PDF? There are many cross platform cli apps that can do that way way much better or could give more control over output (dont know linux, but consider many similar stackexchange etc. questions are answered using for example ghostscript and or image magic)
