The Samsung CLP-320 printer's static ip 192.168.1.139 was set about 10 years ago to work on a lan using 192.168.1.x addresses. Last week the lan's router failed and was replaced with a Netgear r6700 router using 192.168.2.x addresses. The printer is now inaccessible from the lan.

Cups Administration says the printer address can be set using its MAC address:


      Configuring the IP Address Using DHCP

The DHCP protocol is the usual way of setting the IP address of a printer on a managed network. Using the standard dhcpd(8) program supplied with UNIX you simply need to add a line to the /etc/dhcpd.conf file:

host/hostname/  {
   hardware ethernet/mac-address/;
   fixed-address/ip-address/;
}

Make sure that the hostname you use is also listed in the /etc/hosts file or is registered with your DNS server.

apt-cache search dhcpd finds udhcpd. My pc's system is Debian Stretch. There is a file /etc/dhcp/dhclient.conf but no file /etc/dhcpd.

Is it possible to access the printer and change  its address to one in 192.168.2.x or to reset it to use dhcp?



The daemon 'dhcpd' is package 'isc-dhcp-server'.

Can't you change the IP of your ISP router to use the subnet 192.168.1.*?
This is certainly the simplest solution but the Netgear Genie does not have this option even as an advanced setting option. I will contact Netgear by phone to discuss this possibility.


From a web browser if you try to access 192.168.2.1 or 192.168.2.254 do you get a web interface?

If resetting the printer is an option I would do that.
Then you simply change the IP address given by the dhcp server in cups.
