Permanently changing nameserver

[Bruce Labitt]

Due to some ISP snafus, and network reconfiguration, some of my RPI's are
pointing to the wrong nameserver.  I use a pihole for DNS.  Anyways, I have
a single RPI2 as a print server and it is stubbornly pointing to the wrong
IP address.  The RPI2 is running on Raspberry Pi Debian Stretch.  I only
use this node as the cups printer.

If I do cat /etc/resolve.conf I get, # generated by resolvconf  nameserver
192.168.1.xxx
I want to have it permanently point to 192.168.1.1, ie the gateway so that
I let the router redirect DNS traffic to pihole.  Looking at resolvconf
info, it says NOT to use it directly.  So how does one do this?
