c# - How to skip the dialog of printing in printDocument.print() and print page directly?

Question

When I use MyPrintDocument.print() in a Windows application written in C#, a dialog is shown for the Windows processing print routine with a cancel button. I don't want this dialog shown, is it possible?

If not, which way should I use? My program uses a thermal printer.

Which PrintController are you using.

The .NET Framework includes three print controllers that are derived from PrintController that help accomplish common tasks. The StandardPrintController prints a document to a printer. The PreviewPrintController generates a preview of what the document will look like when printed and is used by the PrintPreviewControl and PrintPreviewDialog classes. The PrintControllerWithStatusDialog provides a printing status dialog during the printing process.

It sounds like you are using the PrintControllerWithStatusDialog PrintController.

Caveat: I am not in a position to verify that the basic PrintController doesn't act the same way.

According to this MSDN Forum Posting the PrintControllerWithStatusDialog is the default:

He suggests something like this:

MyPrintDocument.PrintController = new System.Drawing.Printing.StandardPrintController();
