Thank you! You can try moving temporarily all .ppd files from /etc/cups/ppd/ and try running the lpadmin command again. Perhaps if it finds some ppd file already in there with the same settings it won't create a new file. > Can you explain the <IP-address>/ipp vs. <IP_address_here>/BINARY_P1 If you login into the printer's admin GUI with your browser and navigate to Network, Services, you will see a list of service names. You can try configuring CUPS with each one at a time to see what works for you.
