Allow RIP Software to Install or Run when Port 515 is in use

Chances are, you may run into an issue you can't install RIP software ( colorburstrip ) for Canon or Epson printers and the problem is usually caused because of launchd is using port 515.

You can tell this by running this command in terminal:

sudo lsof -i -P | grep 515

If you get an output from this command, you will see usually two lines showing for ip4 and ip6.

To resolve this issue simply uninstall cups-lpd:

sudo launchctl unload /System/Library/LaunchDaemons/org.cups.cups-lpd.plist

To see if it worked for you (even if you get errors) run the first command above again.

If you don't see those 2 lines output, your good to go. Install your software.
