Sure you can install the printer through the CUPS web interface but you may be doing it incorrectly. Are you telling me the install of the AUR package works? Or it doesn’t build? If it does then check the cups web interface again. You may have to remove the printer and add it again but check what you are selecting. Sometimes it has more than one entry for a printer.
Edit: Also have you looked at the wiki as now there is a firewall also to contend with.
Edit2: I read over the previous post and the AUR package was loaded by @joekamprad so it should work.
The AUR package installs OK but printer won’t print in duplex mode. Haven’t tried it on this install of endeavourOS but have tried before, and reviewed the whole issue with @joekamprad in the forum link I mailed before. Finally talked closely to a brother service agent and then we concluded that for some strange reason the AUR package was not working ok, but if I install by using the rpm provided by brother, using rpm-tools, everything worked OK in my last EndeavourOS i3wm install.
You can check this exact comment at the forum post for clarification:
Well that has to be an issue with the usb port? Do you have usb autosuspend turned off? Or some other reason? Have you checked sudo dmesg and or boot logs when trying the printer using journalctl commands?
I haven´t done any specific usb port config
this autosuspend off you mean at the BIOS level? If so, I will check
I haven’t checked any journalctl/dmesg messages
would you recommend any specific commands to try? this would be just after sending the thing to print to cups?
I’m not sure if there is an auto suspend issue or not? You can disable usb auto suspend completely by using a kernel parameter. You could try it i suppose. You add it to the default grub command line and then update grub. If it doesn’t work or causes other issues then you’d have to remove it and update grub again.
Edit: I would suggest trying other usb ports first.
i am with @ricklinux looks a bit like something is going to “sleep” if it is working after a reboot…
Could be the USB port tor the printer… i see similar issue here with my HL-L2350BW and i do not use any driver installed and instead using IPP driverless love network (WIFI) and if printer is a in deep sleep i can not wake it up with try to print…
