Allegedly, on or about 14 September 2016, Angelo Moreschini sent:
lpd://BRN_020554/BINARY_P1
then the hostname 'BRN_020554' needs to resolve to the printer's IP from the server running CUPS
I understand what this means... but I don't know how to accomplice the task: resolve that the IP from the server running CUPS
Any help to do this will be appreciated.
If you have a DNS server, then enter the hostname and numerical IP address into the DNS records (systems using DHCP should do this for you, if they were to work properly, but they usually don't).
If you don't, then you can put it into your /etc/hosts file. Have a look at it, or the hosts man file, to see how it's written.
