No, the lpadmin group should hold only local users (from this localhost). Linux has no nested groups. I would expect that only users that have sudo rights can configure CUPS. This means the user also should be a member of the sudo group (an administrator).

Generally speaking, you should administer CUPS from the local host. If you must do this remotly you can ssh to that host and use the lpadmin commands directly. See... or config the CUPS admin web page to accept the ethernet connection.
redmk2@maui:~$ getent group|grep redmk2
