Plotter Printing : Attribute to determine which side of media to print first

[SoniaBalodi]

Hello,

I am trying to print images of different sizes (A4, A3 and A2) to plotter HP Designjet T520 using cups server and ipp library. There is a requirement to always print long side of the image first.
Can anyone please help with attribute which can be used to specify the same ?
I came across 'media-source-feed-direction' attribute but looks like it is not yet supported in this library.
Also 'finishing-col' seems to have impact on the prints.
It would be helpful if any attribute could be used with current version of library to print long side/short side first.

Regards,
Sonia
