计算机交流平台：计算机故障_计算机论坛 wyC#封装一个打印公共类的简单方法ImagePrinter 类是封装好的打印类，打印前需要调用 public bool PrinterReady(Bitmap printContent) 方法传入一个图片文件，之后就可以调用 PrintView() 进行打印浏览，调用 PrintOut() 就可以打印了。ExpressPrinter 类是调用 ImagePrinter 打印封装类的一个实例，旨在与看看怎么使用GDI+绘制需要打印的内容和字体。=using System;using System.Collections.Generic;using System.Drawing.Imaging;using System.Linq;using System.Text;using System.Drawing;using System.Windows.Forms;using System.Drawing.Printing;using Lib.Biz.ClientService;using Lib.Utility.Extension;using PrintOrder.Utility;namespace PrintOrder.ExpressPrinter.PrintDoc/ / 打印图片内容/ public class ExpressPrinter/ / 创建快递单打印对象实例/ / 打印机名称，如果为空将使用默认打印机/ 打印模板/ 打印项/ 是否打印定位标尺public ExpressPrinter(string printerName, Print_Template template, List items, bool isCoordinateRule)m_template = template;m_items = items;m_print = new ImagePrinter(printerName);m_isCoordinateRule = isCoordinateRule;InitPrinter();#region 变量private Print_Template m_template;private List m_items;private Bitmap m_bitmap = new Bitmap(10, 10);private Brush m_brush = new SolidBrush(Color.Black);private ImagePrinter m_print = null;private bool m_isCoordinateRule = false;#endregion/ / 设置纸张大小/ private void SetPrintPageSize()/使用百分之一英寸为单位重新创建绘图图面using (Graphics g = Graphics.FromImage(m_bitmap)/注：使用百分之一为单位SizeF sizeF = new SizeF(CommonMethod.PixelsToInches(m_template.Width,g.DpiX)*100,CommonMethod.PixelsToInches(m_template.Height,g.DpiY)*100);Size size = Size.Ceiling(sizeF);m_print.DefaultPaperSize = new PaperSize(NewPage, size.Width,size.Height);m_print.DefaultMargins = new Margins(0, 0, 0, 0);m_print.PrintDocName = string.Format(0(1),m_template.TemplateName,m_template.Modifier);/ / 打印前初始化/ private void InitPrinter()SetPrintPageSize(); /设置纸张大小m_bitmap = new Bitmap(m_template.Width, m_template.Height);Func getFont = (o =FontStyle fontStyle = FontStyle.Regular;if (o.FontBold = 1)fontStyle = fontStyle | FontStyle.Bold;if (o.FontItalic = 1)fontStyle = fontStyle | FontStyle.Italic;if (o.FontStrikeout = 1)fontStyle = fontStyle | FontStyle.Strikeout;if (o.FontUnderline = 1)fontStyle = fontStyle | FontStyle.Underline;Font font = new Font(o.FontName, o.FontSize, fontStyle);return font;);using (Graphics g = Graphics.FromImage(m_bitmap)g.PageUnit = GraphicsUnit.Pixel;/填充数据到图片模板（位置要在制作图片模板的时候度量好）g.FillRectangle(Brushes.White, 0f, 0f,m_template.Width,m_template.Height);/测试纸张大小/this.DrawTestRectangle(g);if (m_isCoordinateRule)TestPageSize(g);foreach (Print_Item item in m_items)g.DrawString(item.Text, getFont(item), Brushes.Black, new RectangleF(item.Offset_X + m_template.Offset_X /设置全局打印偏移 X 坐标,item.Offset_Y + m_template.Offset_Y /设置全局打印偏移 Y 坐标,item.Width,item.Height);g.Dispose();/m_bitmap.Save(D:WorkTesttempexpress.jpg);m_print.PrinterReady(m_bitmap);private void DrawTestRectangle(Graphics g)g.PageUnit = GraphicsUnit.Pixel;SizeF size = new SizeF(Utility.CommonMethod.MillimetersToPixel(30, g.DpiX), Utility.CommonMethod.MillimetersToPixel(30, g.DpiY);g.DrawRectangle(new Pen(Color.Black, 1), 50, 50, size.Width, size.Height);/ / 打印标尺/ private void TestPageSize(Graphics g)g.PageUnit = GraphicsUnit.Pixel;/八个定位方格Size size = new Size(20,20);Point ltop = new Point(0,0);Point rtop = new Point(m_template.Width -
