At the last PWG meeting, I agreed to write up proposed wording for several
changes we had asked for in the model document.
Here are some of these changes for your review.  I am assuming that if there is
no comment, these will go into the next version of
the model document as written here ...




4.2.3  copies (integer 1:2**31-1))


This attribute specifies the number of copies to be printed.  On many devices
the supported number of
collated copies will be limited by the number of  physical output bins on the
device, and may be different
from the number of uncollated copies which can be supported. Therefore the
copies-supported attribute
specifies a set of ranges; the first defines the supported range of values for
uncollated copies, and the
second the supported range of values for collated printing.  The set of default
values for copies specify the
default number of uncollated copies followed by the default number of collated
copies.


The effect of this attribute is controlled by the
"multiple-documents-handling" attribute (section 4.2.6).


4.2.19  page-range (1setOf integer)


This attribute specifies the pages of a document which are to be printed. In
most cases, the exact pages to
be printed will be generated by a device driver and this attribute would not be
required. However, when
printing an archived document which has already been formatted, the end user
may elect to print just a
subset of the pages contained in the document. In this case, if page-range =
n.m is specified, the first page
to be printed will be page n. All subsequent pages of the document will be
printed through and including
page m.


Page-range supported is a boolean value indicating whether or not the printer
is capable of supporting the
printing of page ranges.  This capability may differ from one PDL to another.
The page-range default
value is always zero (0) and indicates that all pages of the document will be
printed if a page-range is not
specified.


4.2.20  orientation (type2 enum)


This attribute specifies the orientation of the content on the output pages to
be printed.  In most cases, the
orientation of the content is specified within the document format generated
by the device driver at print
time. However, some document  formats do not support the notion of page
orientation and it is possible to
bind the orientation after the document content has been generated.  This
attribute provides an end user
with the means to specify orientation for such documents.  Standard values are:


'Portrait" (1): The content will be printed across the short edge of the
media.
'Landscape (2): The content will be printed across the long edge of the media.






Media available attribute:


I propose that the current media attribute have the connotation of
"media-ready". That is, the media-
supported attribute represents media actually ready to print To support
production environments where a
printer operator is normally available to load special papers, the following
additional attribute is proposed:




4.2.21  Media-available (1setOf type4 keyword)


In many production printing environments some media, such as special
pre-printed forms, may be
available to be loaded on the printer by an operator when requested. Under
normal conditions, these would
not be reflected in the values of the media-supported attribute, since they are
meant to indicate only what
is normally loaded on the printer and ready to use. However, it is useful for
an end user to know what
media are available to be loaded so that the correct media name can be
specified in the 'media' attribute.
This allows jobs which require special media to be loaded to be queued and
batched together to be printed
once the correct media is loaded.  Thus the attribute not only provides help in
scheduling work but as
input to an operator on how to set up the printer for a particular batch of
jobs.


Since the end-user actually specifies the media to be loaded in the 'media'
attribute, and the default
indicates a ready media, there are no equivalent job and template attributes.
