C#实现包裹面单打印的四种主流实现方式(从 WinForm 到云打印)

using System.Drawing.Printing;

    var pd = new PrintDocument { PrinterSettings = { PrinterName = printerName } };
    pd.PrintPage += (sender, e) =>

        // 使用 Graphics 绘制文本/条码/二维码
        var font = new Font("Arial", 10);
        e.Graphics.DrawString("收件人：张三", font, Brushes.Black, 10, 10);
        e.Graphics.DrawImage(GenerateQRCode("SF123456789CN"), 10, 50);
    };
    pd.Print();
}

var document = Document.Create(container =>

    container.Page(page =>
    {
        page.Size(PageSizes.A6);
        page.Margin(10);
        page.DefaultTextStyle(x => x.FontSize(10));

            column.Item().Image(QrCodeAsBytes("SF123456789CN"));
            column.Item().Text("收件人：张三 138****1234");
        });
    });
