No JobCopiesAllDocuments feature in the xps file generated by XpsDrvSmpl

[sylin211]

I develop a xps driver based on xpsdrvsmpl. When I choose to print multiple copies of a pdf file, only one copy was printed. I unzip the file and open the print ticket file Job_PT.xml and found that there is no JobCopiesAllDocuments feature (about the number of copies) in it.

However, I found that the xps file that generated by Microsoft XPS Document Writer contains this feature (See the picture below).

Does anyone know why xpsdrvsmpl didn't generate this feature? How do I modify the code to generate it?

@sylin211 hopefully somebody will have a look at it as we've seen also issues with XPS but nobody seems to be caring in fixing them:

( @elvis-sun please stop asking in every topic about how to save xps print jobs. Go read the documentation. )
