A success message:
When I run
driverless
'ipp://[fe80::e828:7eff:fe19:9962%25ippusbxd]:60000/ipp/print' > test.ppd
on a current, fully up-to-date Zesty, the file test.ppd contains a valid
PPD file for my printer, meaning that the "driverless" utility (of the
cups-filters package) queried the printer via IPP, talking to it via the
IPv6-based IP address with explicit selection of the interface.
As "driverless" talks to the network using the CUPS library libcups, it
seems that I have found out how to talk IPv6 to CUPS.
Also
ipptool -tv
'ipp://[fe80::e828:7eff:fe19:9962%25ippusbxd]:60000/ipp/print'
get-printer-attributes.test > out.txt
works (needs cups-ipp-tools installed). out.txt contains the IPP
attributes record of the printer after this command.
I can even create a driverless print queue
lpadmin -p DJ2540IPv6 -E -v
'ipp://[fe80::e828:7eff:fe19:9962%25ippusbxd]:60000/ipp/print'
-meverywhere -o PageSize=A4
and actually print on my printer:
lp -d DJ2540IPv6 ~/.quiltrc
So the IPv6 URI works perfectly well with CUPS, problems are now:
- The IPv6 IP does not work with web browsers (Firefox, Chrome; for the
printer's admin interface) and wget.
- I am not able to Bonjour-broadcast my printer with this URI. Probably
one only needs to make this dummy-based "ippusbxd" interface do multicast.
