Printdocument ignoring printer and tray settings

Question

I have a windows service that prints pdf files once it receives a request. It uses PrintDocument, but for some printers it seems to ignore printer and tray settings I give it in my code.

Currently every printer has a few trays which are all installed as seperate queues. For some printers I can just set the PrinterName property (of PrintDocument) to the name of the queue and it works fine. However a couple of printers seem to ignore this. I also tried setting the papersource, but this seems to alway be ignored.

Here's the code used to print:

PrintDocument pd = new PrintDocument();
pd.PrinterSettings.PrinterName = printer; //printer is send to the service along with the request
pd.Print();

Again: this works for some printers, but not for all.

I also tried using Papersource like this:

pd.PrinterSettings.DefaultPageSettings.PaperSource.SourceName = 
    pd.PrinterSettings.PaperSources[tray - 1].SourceName; //Tray is also send with the request

and like this:

pd.PrinterSettings.DefaultPageSettings.PaperSource = 
    pd.PrinterSettings.PaperSources[tray - 1];

What am I doing wrong here?

EDIT: The pdf file always has content in it, so it can't be empty.

I'm printing pdf files that can't be empty (if they are, they never arrive at the service). So there is always content in the files. I should have specified that in the question, sorry. — Dnomyar96

I changed my code to use PrintQueue instead (https://msdn.microsoft.com/en-us/library/system.printing.printqueue(v=vs.110).aspx). This seems to work well, since I can directly call the queues instead of the printer.
