Class OrientationRequested is a printing attribute class, an
enumeration, that indicates the desired orientation for printed print-stream
pages; it does not describe the orientation of the client-supplied
print-stream pages.
For some document formats (such as "application/postscript"), the
desired orientation of the print-stream pages is specified within the
document data. This information is generated by a device driver prior to the
submission of the print job. Other document formats (such as
"text/plain") do not include the notion of desired orientation within
the document data. In the latter case it is possible for the printer to bind
the desired orientation to the document data after it has been submitted. It
is expected that a printer would only support the
OrientationRequested attribute for some document formats (e.g.,
"text/plain" or "text/html") but not others (e.g.
"application/postscript"). This is no different from any other job
template attribute, since a print job can always impose constraints among the
values of different job template attributes. However, a special mention is
made here since it is very likely that a printer will support the
OrientationRequested attribute for only a subset of the supported
document formats.
IPP Compatibility: The category name returned by getName() is
the IPP attribute name. The enumeration's integer value is the IPP enum
value. The toString() method returns the IPP string representation of
the attribute value.
