You could try to "env_keep" XDG_RUNTIME_DIR?
I'm not sure that the above is appropriate. It might be better to
create, for example, "/root/xdg_run/" or "/run/user/0/" and then do
'sudo "XDG_RUNTIME_DIR=<...> system-config-printer"'.
Have you tried gksu/gksudo or kdesudo (or pkexec) for GUI apps? They
might still do the right thing since they're meant for GUI apps.
