Hello! I use Bazzite Linux with KDE, and I’m having some issues with duplex printing on my system.

I have a Brother HL-L2300D, and I’ve already installed the drivers for it. Brother provides an install script for their driver on their website, but because my system is rpm-ostree based and immutable, I would get rpm-ostree errors and the installation would fail.

I found a Reddit post yesterday that suggested running sudo rpm-ostree install printer-driver-brlaser, which worked and I was able to connect to the printer and configure everything as needed.

However, when I try to print on both sides of the page, the back side of the page prints upside-down. I’ve tried changing the setting for which edge to flip when printing (portrait/landscape), and it doesn’t seem to change anything. I printed the same document on a Windows machine on this printer, and it went through just fine, so I’ve isolated the problem down to the CUPS server that my machine is running.

If there’s any more information I can provide, please let me know. I’ve tried the troubleshooting steps I know and have reached the limit of my knowledge.
