Check this.printTicketStore_.copies.isCapabilityAvailable() too.

What is the expected behavior sending PDF with embedded copies to 'Save to PDF'
printer?

[Nikhil, 2014/11/21 10:45:32]

NumCopies property spec doesn't say anything specific to 'Save to PDF' printer.
Please see :
http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf

Also, I tried opening print preview dialog with 'Save to PDF' as printer, and I
don't see copies option in the dialog for both pdf and html pages. 

I think NumCopies should be ignored for 'Save to PDF' printer as we would need
only one pdf file. Please let me know WDYT.

[Aleksey Shlyapnikov, 2014/11/21 22:50:41]

I agree and that's why I suggested to add
this.printTicketStore_.copies.isCapabilityAvailable() check here.

+        this.printTicketStore_.copies.updateValue(
+          event.optionsFromDocument.copies);

Two more spaces indent.

[Nikhil, 2014/11/21 10:45:32]

Done.
