Thank you very much for that. I failed to look as closely as I might have at cups-browsed after reading the CHANGES log for CUPS and a CUPS bug on the subject and made an unwise decision. > Note that when an IPP printer is discovered that always a PPD is generated, > if there is an IPP printer with a known PDL (PWG Raster, PDF, PostScript, > PCL) which does not completely fulfill the IPP Everywhere standard, also a > PPD is generated but capabilities about which the printer does not provide > information are filled in with defaults.

In spite of this extra information I think I'll call it a day after making your suggested change. I usually prefer to write about things I can test and not having an IPP Everywhere printer made me feel handicapped. Cheers, Brian.
