You can modify the security options of the PDF file itself before loading it in the viewer. Using LEADTOOLS SDK, you can encrypt the file and disable options like (editing, copying, printing, etc).
The code would be very simple as follows:
string sourceFileName = @"c:\temp\Leadtools.pdf";
string destinationFileName = @"c:\tempLEAD_EncryptedNoPrint.pdf");

PDFFile pdfFile = new PDFFile(sourceFileName);

// Set the security options
pdfFile.SecurityOptions = new PDFSecurityOptions();
pdfFile.SecurityOptions.UserPassword = "LEAD";

//Disable printing
pdfFile.SecurityOptions.PrintEnabled = false;

pdfFile.SecurityOptions.HighQualityPrintEnabled = false;
pdfFile.SecurityOptions.EncryptionMode = PDFEncryptionMode.RC128Bit;

// Encrypt the file by saving it to the destination file
pdfFile.Convert(1, -1, destinationFileName);
For more information about the security options see this link:

You can give Spire.PDFViewer for .NET a try, it has a PDFDocumentViewer control which allows you to customize the ribbon (you need to download Spire.PDFViewer, add PDFDocumentViewer control from the installation folder to ToolBox, then drag the control into the form):
