VS 2010 PrintDocument Printing to non-default printer

[honeybee]

Something quick. I am trying to print many pages to a printer which is not the default printer.

Here's the code called when the user clicks Print:

        private void GeneratePrint()
        {
            PrintDocument document = new PrintDocument();
            document.BeginPrint += new PrintEventHandler(this.printDocument1_BeginPrint);
            document.QueryPageSettings += new QueryPageSettingsEventHandler(document_QueryPageSettings);
            document.PrintPage += new PrintPageEventHandler(this.printDocument1_PrintPage);
            document.DefaultPageSettings = this.pgSettings;
            this.printDialog1.Document = document;
            this.printDialog1.AllowSomePages = true;
            if (this.printDialog1.ShowDialog() == DialogResult.OK)
            {
                document.PrinterSettings = this.printDialog1.PrinterSettings;
                document.Print();
                return;
                //Other code not relevant
            }
        }

The event handlers for BeginPrint and PrintPage are as follows (QueryPrintSettings handler is empty)

        private void printDocument1_BeginPrint(object sender, PrintEventArgs e)
        {
            this.LoadLayoutData();

            PrinterSettings pSettings = ((PrintDocument)sender).PrinterSettings;
            //Some other code
        }

Here's the PrintPage:

        private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
        {
            //Prepares data for printing this page
            if (pageData[0].IsTopSheet == "True")
            {
                //this.printDocument1.DefaultPageSettings.PaperSource = this.GetPaperSourceForPrinter(this.printDocument1.DefaultPageSettings.PrinterSettings.PrinterName, "Top Sheet");
                e.PageSettings.PaperSource = this.GetPaperSourceForPrinter(e.PageSettings.PrinterSettings.PrinterName, "Top Sheet");
                this.GeneratePrintOutput(e.Graphics, e.PageSettings, pageData, this.TopsheetLayoutSettings, nudgeLeft, nudgeTop);
            }
            else if (pageData[0].IsBottomSheet == "True")
            {
                //this.printDocument1.DefaultPageSettings.PaperSource = this.GetPaperSourceForPrinter(this.printDocument1.DefaultPageSettings.PrinterSettings.PrinterName, "Bottom Sheet");
                e.PageSettings.PaperSource = this.GetPaperSourceForPrinter(e.PageSettings.PrinterSettings.PrinterName, "Bottom Sheet");
            }
            else
            {
                //this.printDocument1.DefaultPageSettings.PaperSource = this.GetPaperSourceForPrinter(this.printDocument1.DefaultPageSettings.PrinterSettings.PrinterName, pageData[0].CommodityCode);
                e.PageSettings.PaperSource = this.GetPaperSourceForPrinter(e.PageSettings.PrinterSettings.PrinterName, pageData[0].CommodityCode);
                this.GeneratePrintOutput(e.Graphics, e.PageSettings, pageData, this.VoucherLayoutSettings, nudgeLeft, nudgeTop);
            }
            this.currentPage++;
            e.HasMorePages = this.currentPage <= e.PageSettings.PrinterSettings.ToPage; // this.TotalPages;
        }

Now the default printer on my machine is an HP model. Since I am testing out the code, I want to print to a non-default printer, which is "CutePDF". I don't want to make this the default printer.

On clicking Print, the print dialog opens fine, and I am able to select CutePDF printer and set other settings. When I click Print from the print dialog, the BeginPrint and the PrintPage events fire in the correct order. When I check the BeginPrint event arguments, the "sender" property correctly points to the CutePDF printer. When I check the PrintPage event arguments, the "sender" property again correctly points to the CutePDF printer, but the "PrintEventArgs e" property still refers to the default HP printer. I am worried this will mess up my printing since I am trying to do some precision printing here, and printer settings would be important.

Why is this happening and how can this be rectified?

Thanks in advance.

Where do you set the value of PageSettings.PrinterSettings.PrinterName ?
That will remain as the default printer, unless it has been changed.

The sequence of events goes (or should go) thus:

I create a PrintDocument (which has an empty/null PageSettings property)
I assign the PrintDocument instance to the PrintDialog and show the PrintDialog to the user
User makes changes in the PrintDialog such as select printer, select number of pages to print etc.
After user clicks Print in the PrintDialog, the PrintDocument.PageSettings should now reflect whatever the user has selected.
So far so good.
The PrintDocument has the BeginPrint and Print_Page event handlers assigned. The moment user clicks Print, the BeginPrint event handler is called - I do my print initialization here.
After BeginPrint, for ever page being printed, the PrintPage event is called. This event takes two arguments: sender - the object which generated this event, and PrintEventArgs which contains more information about the printing - such as the page settings etc. and most importantly the graphics object for the printer.

Now in the PrintPage event, when I check the Sender object, it shows the printer selected by the user by default, but when I examine PrintEventArgs, it always shows the default printer configured in Windows. This means the correct printer object raised the event, but the graphics object which I have to use is of a different printer.

After associating the PrintDocument to the PrintDialog, when the user clicks Print, I check the code and sure enough, PrintDocument.PageSettings.PrinterSettings.PrinterName reflects the printer selected by the user. So I am not sure there's anything wrong in my code.

For now, I have simply set whichever printer I want to print to as the default printer and things are going ok. However this still bugs me a lot.
