As a workaround for mac users, the following steps activate listening to cups broadcasts (thus allowing automatic detection of linux shared printers again):
On your mac use a web browser to open: http://localhost:631/admin/?ADVANCEDSETTINGS=YES
on the right hand side under "server settings" make sure that "Show printers shared by other systems" and "Protocols: CUPS" are checked.
click "save settings"
enter the username and password of an admin account (e.g. your login).
done
