Thanks for the notification. Currently looking into this and how to best patch the PageSize only on non US Machines...

Edit: I think I fixed all of the issues. Thanks and please let me know if I missed something

Important Post-Installation Steps Required

This package has two critical issues that prevent printing from working correctly:

1. Missing Filter Symlink

The filter binary is installed in lpd/x86_64/ but CUPS expects it in lpd/. Create the symlink:

sudo ln -s /opt/brother/Printers/mfcl3760cdw/lpd/x86_64/brmfcl3760cdwfilter \
           /opt/brother/Printers/mfcl3760cdw/lpd/brmfcl3760cdwfilter
sudo chmod +x /opt/brother/Printers/mfcl3760cdw/lpd/x86_64/brmfcl3760cdwfilter

Without this symlink, print jobs complete but nothing prints.

2. Fixed Default Paper Size (Letter instead of A4, important for non-US users)

The configuration file has PageSize=Letter hardcoded, which causes incorrect margins and shifted output regardless of CUPS settings. Fix it:

sudo sed -i 's/^PageSize=Letter/PageSize=A4/' \
    /opt/brother/Printers/mfcl3760cdw/inf/brmfcl3760cdwrc

Without this change, documents print shifted upward with content cut off at the top.

3. Restart CUPS

sudo systemctl restart cups

These issues are identical to those reported for brother-mfc-l8690cdw and brother-mfc-l8390cdw. The PKGBUILD should include: - A post-install script creating the symlink - A patch or sed command to set A4 as default for non-US regions

Maintainer: Please consider adding these fixes to the package. See similar solutions in the AUR packages for brother-mfc-l8690cdw.

There's an issue with this where the driver is looking for the filter in the wrong place and nothing will print if you try to use this. you'll need to install the package and run:

sudo ln -s /opt/brother/Printers/mfcl3760cdw/lpd/x86_64/brmfcl3760cdwfilter /opt/brother/Printers/mfcl3760cdw/lpd/brmfcl3760cdwfilter
