I followed these instructions but no new Printers app under Main Menu > Applications > Preferences > Printers.
To install Bodhi’s Printer Support, click here; this will take you to the Bodhi Linux AppCenter. Click the Install button. This will open the Launch Application window – click on AptURL and then Open link. This will open the eSudo window; type your root password and click OK. This will open the Bodhi Application Installer – click Install. A brief while later, the operation should complete; you may close the Bodhi Application Installer window.
Dunno about missing printer settings.... are you sure you installed the bodhi printing succesfully? [Did you get prompted for password? Did it say it installed successfully?] Just to be sure, I suggest give it a reinstall manually...
sudo apt install --reinstall bodhi-printing
After adding bodhi printer support package and installing the linux drivers with the script from brother website, my printer appeared there automatically. If your printer or a compatible one is listed or detected automatically you may not have to install manufacturers drivers, but I did and worked for me. And for the scanner I installed an app called simple scan.
That didnt work, but.... I found "printers" in settings>apps>favorite applications. So this is solved I can print now with my network Epson L-3150 printer/scanner. Simple san doesnt work, but the epson scanner tool works after adding the right IP
