I was expecting the issue to be something quite simple, but it's actually fairly complicated. Especially considering that the issue only happens with a few printer models, I'm pretty impressed that you managed to find the problem. At least the fix appears quite easy. Seeing that you're modifying the font encoding, could you perhaps reconsider supporting hinting in LMTX? https://mailman.ntg.nl/pipermail/ntg-context/2022/106311.html Even with a high resolution screen, I can still see a difference, and the issue can show up in print too: https://graphicdesign.stackexchange.com/q/5874 I'm fairly confident that these issues are all hinting-related: https://mailman.ntg.nl/pipermail/ntg-context/2022/106874.html https://mailman.ntg.nl/pipermail/ntg-context/2022/105212.html Considering that all of the fonts included with ConTeXt are hinted, it seems like a shame to not include any of that data in the generated PDFs.
