While we said that fonts were outside the scope of IPP V1.0, we could
add it using the registration mechanism after V1.0 is approved.

Now that we have the "document-format" as an input parameter to the
Get-Attributes operation, it would be very useful to have a
Printer Description attribute of "font-supported". Then the proper
PostScript fonts could be returned when the "document-format" input
parameter was 'application/postscript' and would be the PCL fonts
when the input parameter was 'application/vnd.hp-PCL' would return
the PCL fonts. Presumably the attribute syntax would be:

font-supported (1setOf name)

Such an attribute would be a good candidate to propose to the PWG as
an attribute for registration as an extension following the procedures
for registering extensions in the Model document.

ISSUES:

We could even make it a Job Template attribute, like the current
"orientation" attribute which is only for document formats, like
'text/plain' that don't embed the font specification in the document
data. Such an attribute may be more important for Asian countries where
the document format is: 'text/plain; charset=utf-8' or
'text/plain; charset=ISO-10646-ucs-2' (i.e., Unicode)
and they want to select a particular font.
