Hello there,
I’m running Manjaro 5.13 on XFCE, and have been trying to install CUPS and make it work with my printer for a while now.
My printer is a Brother MFC 7340, connected through USB (through a USB-C dongle if that helps). I’ve installed cups, cups-pdf, and brother-mfc7340 from the AUR, and have set up my printer within CUPS.
My issue is that I’m able to send test print commands, and not have any errors / hanging on stuck, but I don’t seem to be able to actually physically print anything out.
I’ve tried blacklisting usblp with modprobe, but that doesn’t affect the problem. I also tried messing with the authentication settings in /etc/cups/cupsd.conf, which also didn’t do anything.
Here’s inxi -Fz:

Here’s the first couple lines of (non verbose) /var/log/cups/error_log:

With verbose logging, I was able to find this, but the file / executable exists on my laptop.
