Observed with 5.18.5 Manjaro and 5.19.0 KDE neon, possibly earlier versions ,too. Working with Netrunner/ Debian 10 with 5.14.5. Changes of printer configuration not effective. For example: paper size and type.
Can you try this with Plasma6?
Meanwhile it works with Manjaro and Plasma 5.27.11. Thanks for asking!
Very good, should be fine with 6 as well, thx.
