C# PrintDocument 打印

进来搞Window打印，发现还是很好弄的，就是在PrintDocument上画，跟在Canvas画一样，要什么样子就画什么样子，先上示例代码

private void button1_Click(object sender, RoutedEventArgs e)

        {

            var printDocument = new PrintDocument();

            //指定打印机

            printDocument.PrinterSettings.PrinterName = "Microsoft XPS Document Writer";

            //设置页边距

            printDocument.PrinterSettings.DefaultPageSettings.Margins.Left = 0;

            printDocument.PrinterSettings.DefaultPageSettings.Margins.Top = 0;

            printDocument.PrinterSettings.DefaultPageSettings.Margins.Right = 0;

            printDocument.PrinterSettings.DefaultPageSettings.Margins.Bottom = 0;

            //设置尺寸大小，如不设置默认是A4纸

            //A4纸的尺寸是210mm×297mm，

            //当你设定的分辨率是72像素/英寸时，A4纸的尺寸的图像的像素是595×842

            //当你设定的分辨率是150像素/英寸时，A4纸的尺寸的图像的像素是1240×1754

            //当你设定的分辨率是300像素/英寸时，A4纸的尺寸的图像的像素是2479×3508，

            printDocument.DefaultPageSettings.PaperSize = new PaperSize("A4", 595, 842);



            printDocument.PrintPage += new PrintPageEventHandler(printDocument_PrintPage);

            try

            {

                printDocument.Print();

            }

            catch (InvalidPrinterException)

            {



            }

            finally

            {

                printDocument.Dispose();

            }



        }

 //打印方法

        void printDocument_PrintPage(object sender, PrintPageEventArgs e)

        {

            var printContent ="打印测试";

            var printFont = new Font("宋体", 12, System.Drawing.FontStyle.Regular);

            var printColor = System.Drawing.Brushes.Black;



            var pointY = 10f;

            //画字符串

            e.Graphics.DrawString(printContent, printFont, printColor, 10f, pointY);

            

            //如何打印带粗体,倾斜,字体中带横线,下划线的字符串,设置字体的FontStyle(粗体,倾斜,字体中带横线,下划线)

            printFont = new Font("宋体", 12, System.Drawing.FontStyle.Bold | System.Drawing.FontStyle.Italic);

            e.Graphics.DrawString(printContent, printFont, printColor, 10f, pointY += 20f);

            printFont = new Font("宋体", 12, System.Drawing.FontStyle.Regular);



            //画图像

            //e.Graphics.DrawImage(Image, 10, 50);



            //设置坐标系缩放

            //设置打印坐标系X值为原值的0.6倍打印

            e.Graphics.ScaleTransform(0.6f, 1.0f);

            e.Graphics.DrawString(printContent, printFont, printColor, 10f, pointY += 20f);

            //恢复坐标系缩放

            e.Graphics.ScaleTransform(1 / 0.6f, 1.0f);

            e.Graphics.DrawString(printContent, printFont, printColor, 10f, pointY += 20f);



            //绘画的设置保存与恢复

            var status = e.Graphics.Save();

            e.Graphics.ScaleTransform(0.6f, 1.0f);

            e.Graphics.DrawString(printContent, printFont, printColor, 10f, pointY += 20f);

            e.Graphics.Restore(status);

            e.Graphics.DrawString(printContent, printFont, printColor, 10f, pointY += 20f);





            //如果打印还有下一页，将HasMorePages值置为true;

            e.HasMorePages = false;

        }

其中Graphics中的方法非常多，大家可以去参考文档，这里只是列出几个常用的，

以下图片就是以上代码打印后的效果

其中的缩放的打印方式不适合针式打印机，缩放后的文字在针式打印机上基本无法查看，后来查看生成的XPS文档，在文档里是图片格式保存的

XPS文档是GZip压缩格式可以使用RAR解压后查看

以下是生成xps文档的目录结构

其中1.fpage就是生成的文档结构，其它目录都是一些相关的资源文件，比如Resources中的Fonts字体文件夹，Images图像文件夹等等

下面是1.fpage中生成的内容，大家可以看出里面的格式就是xml

大家如果想操作xps文档的话可以引用ReachFramework.dll, System.Windows.Xps.Packaging命名空间
里面封装了xps文档的操作方法，这里抛砖引玉顺便介绍了xps的一些知识

顺便贴一个比较详细介绍打印的文件供大家参考
