I’m having a hard time configuring my Brother printer with NixOS. I have brlaser, mfcl2700dnlpr and mfcl2700dncupswrapper installed. Gnome’s printers screen shows the printer but I am unable to print a test page. I also have system-printer-config which I have had success configuring my printer with Gnome in other distributions but no luck.
Thank you! This goes in configuration.nix? I get an undefined variable 'lib' error. I assume this means that I have a misconfiguration somewhere else (I’m pretty new to NixOS).
