It should offer 80, 443, 515, 9100, 631 depending on the protocols it uses. > Then when I point firefox to localhost:631 cups's behaviour has changed.

Hmm ... something must be amiss in your setup. When I go to the Administration tab and click to add another printer the familiar cupsd GUI offers various protocols to choose from. Have you set USE="X"? Bear in mind, I don't use any network upnp autoconfiguration service on my LAN and therefore my use flags may be different to yours: $ equery u cups [ Legend : U - final flag setting for installation] [ : I - package is installed with flag ] [ Colors : set, unset ] * Found these USE flags for net-print/cups-2.3.3-r1: U I + + X : Add support for X11 - - abi_x86_32 : 32-bit (x86) libraries + + acl : Add support for Access Control Lists + + dbus : Enable dbus support for anything that needs it (gpsd, gnomemeeting, etc) - - debug : Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/ wiki/Project:Quality_Assurance/Backtraces - - kerberos : Add kerberos support - - lprng-compat : Do not install lp... binaries so cups and lprng can coexist. + + pam : Add support for PAM (Pluggable Authentication Modules) - DANGEROUS to arbitrarily flip + + ssl : Add support for SSL/TLS connections (Secure Socket Layer / Transport Layer Security) - - static-libs : Build static versions of dynamic libraries as well - - systemd : Enable use of systemd-specific libraries and features like socket activation or session tracking + + threads : Add threads support for various packages. Usually pthreads + + usb : Add USB support to applications that have optional USB support (e.g. cups) - - xinetd : Add support for the xinetd super-server - - zeroconf : Support for DNS Service Discovery (DNS-SD) > Even if I do manage to add the printer, cups reports that it isn't > responding. I take this to mean I'm not using the right protocol. I've > tried IPP, IPPS, HTTP and HTTPS, following that help page. You haven't locked down the printer itself to limit which IP addresses it will allow connections from? Have a look here in case there is some step you've missed out: https://wiki.gentoo.org/wiki/Printing > Package.use is the same as before, and I've tried with cups-browsed both > running and not. > > What am I missing? Cups usually captures informative logs and you can set increased verbosity for more detail. What do these logs report? --nextPart2009736.OBFZWjSADL Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
