Comment 7 for bug 1859685

You can safely ignore any CUPS warnings about deprecated PPD file support functions here. The deprecation in CUPS means that these functions are removed in a later feature release of CUPS (not necessarily the next feature release). The next feature release happens near the end of this year at the earliest, but Google Cloud Print will be discontinued at the end of this year, where google-cloud-print-connector will get useless and therefore removed from the distro. So it does not make sense to migrate the PPD API use to newer IPP-based CUPS APIs.

So the only thing to do here is to not consider warnings as errors in the build of this package and also make sure to use accessor functions for the IPP data structures.

Also do not hesitate to use distro patches in this package, due to the fact that its live ends this year, it is possible that the upstream maintainer does not care about this package much any more.
