I use PDFLibrary.PrintDocument and when I execute my function the printed page is only white.

Here is my code to print a pdf from a Memorystream

DFLibrary.LoadFromStream(PDFStream, '');
printoptions := PDFLibrary.PrintOptions(1, 0, '');
nret := PDFLibrary.PrintDocument(printer, 1, 1, printoptions);

is there something that I forgot?

I would suggest making a call to http://www.debenu.com/docs/pdf_library_reference/RenderDocumentToFile.php" rel="nofollow - RenderDocumentToFile after the LoadFromStream call to ensure that the PDF can be successfully rendered to an image. That will confirm whether the file is loading and rendering correctly. If that is successful then the problem obviously lies with the printing side of things.

When displaying an image of a PDF onscreen or printing one to paper the same rendering process is required, so this will help to see where the problem is.

I have similar problem. I'm trying to print pdf file with printDocument function.
This document is supposed have an image (it is a scan) on the first page and a text on the second page.

The problem is that printout contains first blank page where supposed to be an image (the second page is correctly filled with text)

I tried to use renderDocumentToFile function and it gives same result.
When I just save the document and reopen, both text and image are present.

my code:

var QP = new QuickPDF();
DebenuPDFLibraryDLL1014.PDFLibrary pdf = QP.unlockLibrary();

string f = "C:\temp\file.pdf";
pdf.LoadFromFile(f, "");
int n = pdf.PageCount();
string printer = pdf.GetDefaultPrinterName();
int result = pdf.PrintDocument(printer, 1, n, 0);
