Isn't listening on 0.0.0.0 instead of localhost only needed if the machine itself is hosting a printer that needs to be accessible to other hosts?
- mikepavone 2y agoI am very unfamiliar with the protocol, but my impression from a little reading is that the sharing computer broadcasts and the receiver listens. This appears to be for some CUPS specific browsing/discovery protocol rather than mDNS/DNS-SD (cups-browsed supports adding printers discovered that way but depends on avahi to handle the mDNS part). EDIT: Here's a description of the protocol in question: https://opensource.apple.com/source/cups/cups-327/cups/doc/help/spec-browsing.html https://opensource.apple.com/source/cups/cups-327/cups/doc/h...
- tsimionescu 2y agoNo, per the article, cups-browsed is used so that a printer can register itself to your system. The printer is the one that initiates a connection to tell your system that it is available at some URL.
