"media-col" support (and the corresponding "media-size-supported" attribute) is not required for IPP/2.0, but it *is* required for IPP Everywhere and AirPrint (which Lexmark claims this printer supports).

It would probably be good to check for firmware updates (there have been several over the last year for most of Lexmark's printers) and, if that doesn't resolve the problem, contact Lexmark about the issue.

In the meantime, please do file an issue about this for CUPS at:

We can easily add code to the IPP Everywhere PPD generator that uses "media-supported" as a fallback.
