C # print principle (including code)

Recently, a charging system was completed, and the customer requested a complicated printing format. He wanted to use word as a template for printing, but then the customer changed the printing format, even wrod cannot do that format. Therefore, I tried to print the image as a template.

I think the printing principle is: generate an MDI file. When the system encounters an MDI file, it will automatically print the file. Therefore, no matter what template or method is used, you can generate an image to print the content in the printpage event processing! (If it is an incorrect understanding, please point it out !)

{
// Print and preview
// Printpreviewdialog PPD = new printpreviewdialog ();
Printdocument Pd = new printdocument ();
// Set the margin
Margins margin = new margins (20, 20, 20, 20 );
PD. defaultpagesettings. Margins = margin;
/// Set the default value for the paper
// Papersize pagesize = new papersize ("first custom size", 800,600 );
// PD. defaultpagesettings. papersize = pagesize;
// Print event settings
PD. printpage + = new printpageeventhandler (this. pd_printpage );
// PPD. Document = Pd;
// PPD. showdialog ();
Try
{
PD. Print ();
}
Catch (exception ex)

MessageBox. Show (ex. message, "print error", messageboxbuttons. OK, messageboxicon. Error );
PD. printcontroller. onendprint (PD, new printeventargs ());
