Multiple Copies Print

In your Crystal Report ensure that you have placeholders for the text that should be printed (e.g., "Original" and "Duplicate").

ReportDocument report = new ReportDocument();
report.Load("path_to_your_report.rpt"); // Load your Crystal Report file

// Create a parameter to allow the user to select Original, Duplicate, or Triplicate
ParameterFieldDefinition parameterField = report.DataDefinition.ParameterFields["PrintOption"];
report.SetParameterValue("PrintOption", "Original"); // Set the default value to "Original"

// Get the selected parameter value
string printOption = GetUserSelectedOption(); // Implement a method to get the user's selection

if (printOption == "Original")
{
    report.DataDefinition.FormulaFields["PrintText"].Text = "Original";
}
else if (printOption == "Duplicate")
{
    report.DataDefinition.FormulaFields["PrintText"].Text = "Duplicate";
}
else if (printOption == "Triplicate")
{
    report.DataDefinition.FormulaFields["PrintText"].Text = "Triplicate";
}

int numberOfCopies = (printOption == "Triplicate") ? 3 : 2;
report.PrintToPrinter(numberOfCopies, false, 0, 0); // Print the report

report.Close();
report.Dispose();
