#HowTo get Brother Printer (HL-3142CW) to print

I tried installing the printers automatically through Software, but this didn’t work because they are proprietary.

I was able to install the LPR and CUPS drivers as RPMs from the Brother website for driver downloads, but this did not work either.

Eventually, I found this forum topic for Fedora 26. I was able to print test pages from http://localhost:631/printers and the PDF I needed to print after running the following:

sudo dnf install glibc.i686 psutils
sudo setsebool -P cups_execmem 1
