Ok, I can see that. With document-format isn't the deal that you can
any mime-media type, defined by RFC, or an arbitrary string? That would
you the base level of standardization that everyone could count on
that there's an equivalent for media formats like there was for document
data formats), without limiting proprietary extensions that may be
in some cases.
I'm not sure that just having a single "custom" value is good
like to be able to reference my own media type by a name that makes
me, not by "custom" with a definition each time. "bonus stickers" might
a value I want to use for media type...and it might make sense to my
programmable printer, where it's equal to "bin 1" or "make operator
with that name" or something. If there was a "media-types-supported"
in the get-printer-attributes reply, I could even present such a thing
user for them to select if they want to.

No problem with that as a base, I just wouldn't like to see it stop
I want to be able to extend the media type names that are available,
because the printer knows them, or because it can be told what to call
things that it knows about (alias naming?) to more closely match user
expectations for various forms of media (Purchase Order Forms,
etc.). The client doesn't have to have things hardcoded...they can be
configuration settings, or acquired from the printer through query. My
client will accept anything the user cares to enter for most items, and
overrules when there's a printer attribute that the client has received
says it isn't going to work (i.e. user asks for 1000 copies on a printer
with a valid copies range of 1:99).
I don't want to waste your time on this if all this has been handled.
trying to offer a suggestion in case it wasn't already ruled out for
reason. Like I said, I haven't followed the entire discussion on this
I've been implementing my IPP client... (now in beta test! :^)
Thanks for reading. If it's useful, feel free to pass it on, if it's
then just ignore me. :^)
