"media-type-supported" only searched using IPP_TAG_KEYWORD format #397

Closed jstrine closed 3 years ago

jstrine commented 3 years ago

Some printers (example HP ColorLaserJet M281fdw) list media-type-supported in IPP_TAG_NAME versus IPP_TAG_KEYWORD format. cups-filters/driverless will not write the media-types to the PPD, but the cups/ippeverywhere driver will.

Value returned from printer media-type-supported (1setOf nameWithoutLanguage) = ...

Matching cupsfilters/ppdgenerator.c to CUPS cups/ppd-cache.c, shows CUPS project uses IPP_TAG_ZERO to match wildcards and correctly write the PPD.
