7 months ago looking at the code, I think if you duplicate the value of physical_printer_name to a key simply named name that should fix the latest error. I've also pushed a fix to fall back to physical_printer_name if name isn't set so you could just update to the latest version of master as an alternative!
Describe the bug Can't get libki to send print jobs to cups. Cups can print, libki can't find the printer.
To Reproduce Steps to reproduce the behavior:
Installed libki with the debian install script from the manual from the documentation site.
setup as normal with cups printing
installed cups locally, setup user lp to be allowed to print, added a brother print
tested brother printer from the cups admin and
lp -d Brother_DCP-7065DN test.txtworks.after a lot of testing I finally noticed the first issue. It's worth noting the rest of the system is working as expected, clients can connect and print jobs get sent from client folders to the libki server and the file adds the ".printed" extension indicating the job arrived at libki at least.

Expected behavior Expected after setting up yaml, configuring authentication to allow the lp user to print that libkey would send jobs to the local cup service.

Additional context
I don't know if the install script isn't installing everything needed for cups to work but I'm fairly certain this is a bug and not a configuration problem at this point. I'm not a programmer so, I think I've hit as far as I can take this.
