To restrict printing operations with a PDF document, create a PdfEncryptionOptions object using the PdfSaveOptions.EncryptionOptions property and specify the owner password using the PdfEncryptionOptions.OwnerPasswordString property, and printing permissions using the PrintingPermissions property.
The owner password allows a user to have full access to a document.
Note
The restrictions on data extraction, data modification, interactive, or printing operations with a PDF document can’t be applied without the owner password.
For more information, see the Document Protection topic.
#Example
This example shows how a PDF document can be protected using both the owner and user passwords.

{
using (PdfDocumentProcessor pdfDocumentProcessor = new PdfDocumentProcessor()) {
// Load a PDF document.
pdfDocumentProcessor.LoadDocument("..\\..\\Demo.pdf");
// Specify printing, data extraction, modification, and interactivity permissions.
PdfEncryptionOptions encryptionOptions = new PdfEncryptionOptions();
encryptionOptions.PrintingPermissions = PdfDocumentPrintingPermissions.Allowed;
encryptionOptions.DataExtractionPermissions = PdfDocumentDataExtractionPermissions.NotAllowed;
