c# - 如何在 Crystal Report 中显示打印对话框？

Question

我想Crystal report直接打印到打印机。目前我正在出口到PDF. 但我的客户希望它直接进入打印机。如何显示Print Dialog单击打印按钮以将报告直接打印到打印机。

我想提一下：我正在为我的项目使用 C# 和 asp.net。

谢谢你。

Answer 1

试试下面的代码

    private void Button1_Click(object sender, EventArgs e)
    {
        CrystalReport1 report1 = new CrystalReport1();
        PrintDialog dialog1 = new PrintDialog();

        report1.SetDatabaseLogon("username", "password");

        dialog1.AllowSomePages = true;
        dialog1.AllowPrintToFile = false;

        if (dialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {
            int copies = dialog1.PrinterSettings.Copies;
            int fromPage = dialog1.PrinterSettings.FromPage;
            int toPage = dialog1.PrinterSettings.ToPage;
            bool collate = dialog1.PrinterSettings.Collate;

            report1.PrintOptions.PrinterName = dialog1.PrinterSettings.PrinterName;
            report1.PrintToPrinter(copies, collate, fromPage, toPage);            
        }

        report1.Dispose();
        dialog1.Dispose();
    }

您必须使用数据库的凭据更改“用户名”和“密码”。

此代码仅可用于服务器端打印。

没门; Cristal Report Viewer 用于显示和浏览报告。
它从不显示所有报告页面。
它没有直接打印的按钮或方法。

相反，您可以直接以 PDF 格式导出报告，这样用户就不会看到报告查看器，并且打印变成一键式操作。

                                   System.Drawing.Printing.PrintDocument printDocument1 = new System.Drawing.Printing.PrintDocument();
                                    //Get the Copy times
                                    int nCopy = printDocument1.PrinterSettings.Copies;
                                    //Get the number of Start Page
                                    int sPage = printDocument1.PrinterSettings.FromPage;
                                    //Get the number of End Page
                                    int ePage = printDocument1.PrinterSettings.ToPage;
                                    crReportDocument.PrintOptions.PrinterName =printDocument1.PrinterSettings.PrinterName;
                                    //Start the printing process.  Provide details of the print job
                                    crReportDocument.PrintToPrinter(nCopy, false, sPage, ePage);

// Form_Printerd = true; }
