[cups-devel] How to get a list of (or default) page size?

[Michael Sweet]

Olivier,

I'm not aware of any issues with this API.  Can you file a bug on CUPS.org for this:

    https://www.cups.org/str.php

Also, it would be helpful if you tested using the current stable release of CUPS (1.7.2) rather than a release candidate...

Thanks!
