Amazing how an extrrra r or two can creep in.

Looks like cups doesn't start up. 'systemctl status cups.socket' might
have been a better command to try. There is also 'systemctl start

This looks like the default file (apart from 'SystemGroup lpadmin',
which should be in another file and which doesn't matter). The list is
very tolerant of a file less than 5 kB in size. Also, in time it doesn't
disappear and is easier to work with.

The commented line (which you omitted) before these two has some
importance. It's never a good thing to edit when seeking help.

There are a number of ways to get 'lpstat: Bad file descriptor'. Most do
not apply to you. My only guess is that you have disabled ipv6.

   cat /proc/sys/net/ipv6/conf/all/disable_ipv6
