I am having some trouble specifying multimedia jobs in IPP. One example
would be a small saddle-stitch brochure, where the outside is printed on
heavy card stock to make a cover.
I could submit such a job as two documents. One A4 document for the cover,
and another A5 document for the internal pages. I could then specify
finishing=saddle-stitch and
multiple-document-handling=single-document-new-sheet and media=iso-A5. All
this specifies that the two documents should be imposed as an A5
saddle-stitch document on A4 sheets and bound together.
The only thing I cannot do is to specify that the first document, the cover,
ought to be printed on heavier stock.
Section 4.2.6 of the MOD states:
'6' 'cover': This value is specified when it is desired to select
a non-printed (or pre-printed) cover for the document.
This does not supplant the specification of a printed
cover (on cover stock medium) by the document itself.
This implies that a document can specify a medium, but I don’t see how to do
this. It looks as if the Send-Document request ought to use more of the job
attributes. It has document-name, document-format, compression and a couple
of others. It seems that each document within a job ought to be able to
specify sides, number-up, orientation-requested, media, printer-resolution
and print-quality as well. If one of these attributes are not specified for
a document, then the value specified for the job would apply.
In the example above, the cover should be printed with
sides=duplex-short-edge orientation-requested=landscape because it is an A4
sheet and the colors bleed all the way across. The contents should be
printed with sides=duplex-long-edge orientation-requested=portrait because
they are A5 portrait size.
A similar problem occurs when printing letters and envelopes for a mail
shot. I could submit a document with 500 addresses and a document with 500
corresponding letters and specify
multiple-document-handling=single-document-new-sheet. I don’t have a way of
specifying that the first document should be printed on envelopes and the
second on letter stock. There is also the same problem with orientation and
duplex settings.
What do the rest of you think of this? Perhaps what I want to do is
possible and I have just not read the spec carefully enough, but it looks as
if more document attributes would be useful, even for quite simple printers.
