Re: handling of printer-more-info in CUPS

[ CCed the developers for driverless IPP printing support in the printer setup
   tools of the GNOME, KDE, and COSMIC desktops ]

Armin,

thanks for the hint with "printer-more-info" in the printer properties reported 
in response to a "get-printer-attributes" IPP request and that the functionality 
accessible through this URI is often not accessible via the standard web admin 
interface of the same printer.

Anybody developing printer setup tools,

according to Armin's findings, it seems that for each IPP print destination 
listed by the printer setup tool there should not only be a button for opening 
the standard web admin interface, but also, if a "printer-more-info" attribute 
is reported, a button to open the link provided by this attribute.

Also, the "get-printer-attributes" IPP response should be checked for other 
interesting URI-type attributes which could deserve/need a button in the printer 
setup tool. Michael (Sweet), as master of IPP, anything worthwhile here?

    Till
