I just updated python-cups to a new version, and it is now shipping files to automatically add Provides tag to packages that are shipping cups drivers (thanks to the new rpm 4.9).
It's matching those files: %__psdriver_path ^(/usr/lib/cups/driver/.*|%{_datadir}/cups/drv/.*\.drv)$ %__psdriver_magic ^PPD file.*$
It'd be cool to have all our packages that are shipping drivers for cups use this. It's just a matter of adding a python-cups BuildRequires.
For instance, for gutenprint, this would add Provides like this: postscriptdriver(hp;photosmart_100;)
This will enable configuration tools to know which package to install, if one is needed, when configuring a printer.
I've submitted the change to gutenprint, so you can take a look at it to if you need to change another package in a similar way (but it's really easy): https://build.opensuse.org/request/show/71723
How did it work for you when you tested it? Are those Provides somehow special so that "rpm -q --provides" does not show them? If those Provides are regular RPM Provides, I wonder if it is really a good idea to have thousands of such Provides in the RPMs because there are thousands of printer models. Are there already "configuration tools" which use those Provides? Do system-config-printer and udev-configure-printer already use them?
