I am developing an application that creates a label with text and barcode using PDF API and printing through PDFViewer API. However, I cannot seem to correctly print the PDF label on a Zebra thermal printer. Below are the actual PDF label sample, print output using Acrobat Reader, and print output through PDFViewer.
PDF label output
Acrobat reader print output
PDFViewer print output
As you can see, the printing is almost OK with Acrobat reader but rotated when printed using PDFViewer. Also, I cannot seem to silently print through code, whether through a stream or by saving to PDF first. I was able to print only when pdf file was opened in PDFViewer. Below is my code for printing the label, the commented lines are for the other printing options (through a stream).
private void PrintBarcode()
{
// Initialize print dialog.
viewer.Load(Application.StartupPath + @"\barcode.pdf");
//viewer.Load(stream);
viewer.PrintDocument.DocumentName = "BG Label";
//viewer.PrintDocument.Print();
viewer.Print(false);
//stream.Dispose();
}
By the way, would like to ask for advice if this is the best way to implement a label designer and print it in Windows forms. I know there is a separate barcode control but printing it with text seems cumbersome.
