directPrintPdf multiple copies

[Pebkac03]

Is your feature request related to a problem? Please describe.

When using directPrintPdf you are unable to specify number of copies.

Describe the solution you'd like

in printing/windows/print_job.cpp on lines 114-132 it seems to be that this is an option that can be specified since nCopies is set to a default of 1 when using layoutPdf to print using a print dialog. I do not know C++ so I realise I might be wrong but to me this indicates it is a parameter that can be specified.

Describe alternatives you've considered

I have read previous closed issues where using a for loop in dart to send multiple identical printjobs was suggested but it seems to me this is worse practice, or is the result identical from the printer/printer-driver's point of view?

Additional context

Any updates on this feature?? I'm using the for loop right now, but I've noticed that printing is slower this way than when you set the number of copies in the iOS popup.
