4x6 Label not rotating or sized right

I have a PDF that is set as a 4x6in document meant for thermal 2844 zebra printers. Opening up the document in Foxit or Acrobat and printing it works fine to this printer but using QuickPDF, it just makes it real small (almost like a 2x3 or something).

I can't force size this as we will be printing PDF to any number of printers, laser and thermals... Any idea if im missing something?

Here's my code

        Dim pdfData As Byte() = CType(arg, PrintArguments).LabelImage()
        Dim sPrinterName As String = CType(arg, PrintArguments).PrinterName()
        Dim sPFDFile As String = CType(arg, PrintArguments).FilePath()

        QP = New QuickPDFDLL0723.PDFLibrary("QuickPDFDLL0723.dll")

        If QP.UnlockKey("my_reg_key") = 1 Then

            Dim pdfStream = New MemoryStream()

            pdfStream.Write(pdfData, 0, pdfData.Length)

            Dim DocumentID As Integer = QP.LoadFromString(pdfData)

            If DocumentID > 0 Then
                Dim OptionsID As Integer = QP.PrintOptions(2, 1, "Document")
                QP.PrintDocument(sPrinterName, 1, QP.PageCount, OptionsID)

                QP.RemoveDocument(DocumentID)

            End If
        End If

Anyways, I think i figured it out.  Im using a windows service to spit out PDFs and the service is using a Login user to impersonate which if I would log into that user, had the printer settings at 2x3 rather than 4x6.  

So basically, it was working.  My weird setup was causing the problems.

Thanks though.  :)
