通用打印

这里的打印采用graphic去画出来，所以，可以根据不同的要求随意的设计模板。同时可以通过图片的形式加载模板。代码如下，此实例参考了网上的一些文章，具体的文字位置不是很准，只做演示：

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

 

        private void btnPrint_Click(object sender, EventArgs e)

        {

            //打印预览

            PrintPreviewDialog printPreview = new PrintPreviewDialog();

            PrintDocument printDocument = new PrintDocument();

            //设置边距

            Margins margin = new Margins(20, 20, 20, 20);

            printDocument.DefaultPageSettings.Margins = margin;

 

            //纸张设置默认

            PaperSize paperSize = new PaperSize("First custom Size", 800, 600);

            printDocument.DefaultPageSettings.PaperSize = paperSize;

 

            //打印事件设置

            printDocument.PrintPage += new PrintPageEventHandler(printDocument_PrintPage);

            printPreview.Document = printDocument;

            printPreview.ShowDialog();

 

            try

            {

                printDocument.Print();

            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.Message, "打印出错", MessageBoxButtons.OK, MessageBoxIcon.Error);

                printDocument.PrintController.OnEndPrint(printDocument, new PrintEventArgs());

            }

        }

 

        void printDocument_PrintPage(object sender, PrintPageEventArgs e)

        {

            string date = DateTime.Now.Date.ToShortDateString();//当前日期

            string flowID = "20110308";//流水号

            string payDate = DateTime.Now.Date.ToShortDateString();//应收日期

            string adminID = "12345678";//操作员编号

            string baseExpense = "2000";//应交基本费用

            string fine = "500";//应交罚款数目

            string upExpense = "5000";//上月结余

            string actualExpense = "2500";//实际应交数目

 

            //读取图片模板

            Image temp = Image.FromFile(@"3dbg.jpg");

            GetResultIntoImage(ref temp, flowID, date, baseExpense, fine, upExpense, actualExpense, payDate);

            int x = e.MarginBounds.X;

            int y = e.MarginBounds.Y;

            int width = temp.Width;

            int height = temp.Height;

            Rectangle destRect = new Rectangle(x, y, width, height);

            e.Graphics.DrawImage(temp, destRect, 0, 0, temp.Width, temp.Height, System.Drawing.GraphicsUnit.Pixel);

        }

 

        /// <summary>

        /// 将收费结果填充到图片模板

        /// </summary>

        private void GetResultIntoImage(

            ref Image temp,

            string flowId,

            string currentDate,

            string baseExpense,

            string fine,

            string upExpense,

            string actualExpense,

            string payDate)

        {

            //读取图片模板

            Graphics g = Graphics.FromImage(temp);

 

            Font f = new Font("宋体", 12);

            Brush b = new SolidBrush(Color.Black);

           

            //填充数据到图片模板位置（要在制作图模板的时候度量好）

            g.DrawImage(temp, 0, 0, temp.Width, temp.Height);

            g.DrawString(flowId, f, b, 335, 105);

            g.DrawString(currentDate, f, b, 335, 134);

            g.DrawString(baseExpense, f, b, 19, 202);

            g.DrawString(fine, f, b, 172, 202);

            g.DrawString(upExpense, f, b, 286, 202);

            g.DrawString(actualExpense, f, b, 396, 202);

            g.DrawString(payDate, f, b, 176, 269);

 

            g.Dispose();

        }

    }

 

 即使是更加复杂的打印，也可以采用同样的道理打出来，只需要校准好位置即可。为了演示，文中的字段值都是直接简单赋值，当然可以采用从输入设备中读取的值。
