When updating from the stable 3.8.x series, please bear in
mind that your edits will be preserved during this process, but the new
library and configuration will no longer be usable with 3.8.x.
I’ve tried to merge DNGs from my Android phone (a OnePlus 6T) before and they would always end up with a black output. This sounds like it would fix this issue, but it still results in black DNGs. How do I properly open a bug report with problematic DNGs attached?
The print module has never been ported to Windows which is lacking contributors. If you are a dev or know a dev working on windows willing to help it would be nice We have said many time that we need more people working on Windows, there is no magic.
The alternative is very simple though, move to GNU/Linux and you’ll have the print module
Then it means that the distro did not compile darktable with libcups installed. I know for sure the print module is working as I’m using it almost once a week. There is many optional dependencies for darktable, each one activating some specific support like the print module or the map view (need the libosmgpsmap), or support for external formats like AVIF, J2K, HEIF… So if you find some missing piece just report upstream, the darktable team cannot do something about this.
