The macOS system must disable Printer Sharing.

Printer Sharing must be disabled.

Verify the macOS system is configured to disable Printer Sharing with the following command:

/usr/sbin/cupsctl | /usr/bin/grep -c "_share_printers=0"

If the result is not "1", this is a finding.

Configure the macOS system to disable Printer Sharing with the following commands:

/usr/sbin/cupsctl --no-share-printers /usr/bin/lpstat -p | awk '{print $2}'| /usr/bin/xargs -I{} lpadmin -p {} -o printer-is-shared=false
