Question

例如，我有一个标签可以打印，如下例所示，现在如果我要制作3份副本，如何在我正在打印的标签中的某处打印副本号？

示例代码：

Private Sub btnPrintProcLabel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPrintProcLabel.Click
        If ValidateData() Then
            AddHandler PrintDocument1.PrintPage, AddressOf PrintProcLabel

            Try
                PrintDocument1.PrinterSettings.PrinterName = SinglePrinter.PrinterSettings.PrinterName
                PrintDocument1.PrinterSettings.Copies = CInt(txtCopies.Text)
                PrintDocument1.Print()
            Catch ex As Exception
                MsgBox(ex.Message)
            End Try
        End If
    End Sub

Public Sub PrintProcLabel(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs)
        Dim g As Graphics = e.Graphics
        Dim br As Brush = New SolidBrush(Color.Black)
        Dim pn As Pen = New Pen(br)

        g.DrawString(Today.Month & "/" & Today.Day & "/" & Today.Year, Arial, br, 250, 3)

End Sub

Answer 1

   PrintDocument1.PrinterSettings.Copies = CInt(txtCopies.Text)

告诉打印机驱动程序生成副本，它们都是相同的。如果你想给它们编号，那么你需要自己创建“副本”。它们不再是真正的副本，因为它们都会略有不同。只需使用一个计数器重复调用Print（）方法，该计数器的值是PrintPage事件处理程序中的DrawString（）。

如何使用system.drawing.printing.printdocument vb.net打印副本号
