Are you suggesting that just identifying the document-format as 'image/tiff'
For conformance in IFAX using IPP, we may need to specify that image/tiff
includes some particular profile. Or are you suggesting that we need to
specify the profile in the value of the IPP "document-format" attribute in
Does the submitter (client software) have to identify the profile being used
in what is being submitted to the IPP Printer, or is it sufficient for the
IPP Printer to indicate the profile or profiles that it will accept and
image correctly for documents submitted with the document-format attribute
indicating 'image/tiff'? If the latter is sufficient, we could just add a
Printer Description attribute, say, tiff-profiles-supported, in which the
printer lists the tiff profiles that it supports. Such an attribute would
not be submitted with the document, but would be queriable using
If the submitter has to identify the profile being passed, then we would
need to add a new Job Template attribute (or may a new Operation attribute?)
that indicates the "tiff-profile" being submitted. This attribute would
only be submitted when the "document-format" attribute also being submitted
