No, neither on cups server, nor on cups client

Not installed, both systems client and server are Debian buster.

Which user? My user on the client yes:
rd@h370:~$ groups
rd adm dialout fax cdrom floppy sudo dip video plugdev users lpadmin scanner
docker vboxusers i2psvc wireshark sispmctl
rd@h370:~$

Not sure if I understand this one.
The problem became worse, it seems to be intermittent, it is gone right now
(but I am sure it will eventually come back).
Thanks

See client.conf(5) and https://lists.cups.org/pipermail/cups/2015-October/055525.html -- Brian.
