One option is to abandon using HPLIP and use driverless printing. It would
be splendid if you would have the 6968 wireless connected and gave the
outputs of

  avahi-browse -rt _ipp._tcp
  avahi-browse -rt _uscan._tcp
  driverless

The HP 6068 is connected wireless. Attempted the suggested commands. I'm probably missing something. I'd also like to have the HP 6068 scanner working as well. Here is the result

You have a network problem. libnss-mdns is installed? The printer
can be pinged? Firewall? What does 'ippfind -T 5' give?

That's on the cards with a working network.

The problems with missing dependences can occur while upgrading Ubuntu instead of fresh installation.
Solution is here: https://www.linux.org/threads/satisfying-dependencies-for-installation-of-hplip.29842/

in short following commands can help you:

root@xxxxx:/usr/bin# ls -lrth python*
lrwxrwxrwx 1 root root 9 Apr 16 2018 python -> python2.7
-rwxr-xr-x 1 root root 3.6M Nov 12 2018 python2.7
-rwxr-xr-x 2 root root 4.4M May 7 14:58 python3.6
In above example if you see the output of python --version you will get python2.7 Now update the python symlink using below command-

Code:

root@irshad:/usr/bin# unlink python
root@irshad:/usr/bin# ln -s /usr/bin/python3.6 python
root@irshad:/usr/bin# python --version
Python 3.6.8
