Not sending DNS information to selected clients.

[SMF Forum 1]

I have a problem with a phantom network printer in my cups printing
environment.
The cups people have suggested that I turn off dns for the network
printer in question to resolve this.
How do I correctly amend the dhcpd.conf to achieve this ie not send a
DNS ip addess for this device and only this device.

The version of dhcpd is isc-dhcpd-4.4.2-P1.

The header of my dhcpd.conf file is as follows:

authoritative;
default-lease-time 43200;
max-lease-time 86400;
option custom-proxy-server code 252 = text;    
option custom-proxy-server "http://wpad.dat";

subnet 192.168.0.0 netmask 255.255.255.0 {
    range 192.168.0.90 192.168.0.128;
    option domain-name "delta";
    option domain-name-servers 192.168.0.1;
    option routers 192.168.0.1;
    option ip-forwarding on;
    option broadcast-address 192.168.0.255;
    option subnet-mask 255.255.255.0;
    option ntp-servers 192.168.0.1;
}

The entry for the printer currently reads as follows:

host hp6020e {
    hardware ethernet e0:70:ea:72:6f:10;
    fixed-address hp6020e.delta;
}


Thanks
