PDF file prints as blank page

I am using c# and QuickPDF Library 7.13 to print PDF documents.  A PDF document with a page size = letter prints OK on a letter sized piece of paper but PDF documents that have a page size bigger than letter size, for example 9.84 x 13.94 in., only produce a blank printed page.  PageScaling is switched on which I thought would take care of printing larger page sizes onto a letter size piece of paper.  Is PageScaling the right approach to print PDF documents that have a page size greater than letter size?  Is there something else that I am overlooking?

The code that is being used follows the sample code included in the QuickPDF library:
string PrinterName = qp.GetDefaultPrinterName();
int StartPage = 1; // Set first page number
int EndPage = qp.PageCount(); // Set last page number
// Set the paramters for the PrintOptions function
int PageScaling = 1;
int AutoRotateCenter = 0;
string Title = fileName;
// Assign the options for printing to an int variable
int Options = qp.PrintOptions(PageScaling, AutoRotateCenter, Title);
// Print the document with the required paramters and options specified
qp.PrintDocument(PrinterName, StartPage, EndPage, Options);
