SOLVED cups stopped working

Postby Berforfree » 2019-11-21 18:47

Debian 10.2 xfce
cups installed and did work well for long, no idea when stopped working
Since sending something to printer wasn't possible, I removed the network printer, tried to add it again with no success
from System --> Print Settings --> add IP select IPP--> cups server error
if I try through the web page --> http://localhost:631/help/network.html --> Not found

Here some output that might help
