private void printDoc_BeginPrint(object sender, System.Drawing.Printing.PrintEventArgs e)

            printDoc.PrinterSettings.PrinterName = @"\\192.168.135.130\HP LaserJet Professional P1108";   //“打印机名称”;
        }

        private void printDoc_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)

            Graphics MyGraphics = e.Graphics;
            SolidBrush drawBrush = new SolidBrush(Color.Black);
            Font drawFont = new Font("黑体", 10);       //字体和大小
            MyGraphics.DrawString("打印内容1", drawFont, drawBrush, 0, 0);
            MyGraphics.DrawString("打印内容2", drawFont, drawBrush,0,100);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            this.printDoc.PrintPage += new PrintPageEventHandler(this.printDoc_PrintPage);
            printDoc.Print();
        }

以前发的，打印的里面都有，应该比较全了
http://bbs.
全部源码无DLL的坑，收费的只是功能多点、bug少点。代码都差不多

MyGraphics.DrawString("打印内容2", drawFont, drawBrush,30,100);
请问这30和100是什么单位，是英寸还是厘米？

像素，dpi96下我是这么转换
pf.Paper_Area = new Size(
                    (int)Math.Floor(宽度 * 3.779527559055118),
                    (int)Math.Floor(高度 * 3.779527559055118)
                    );
