在C#中利用Graphics 直接打印文字、方框、横线等内容

1、添加控件

      在winform中添加如下printDialog、printDocument1、printPreviewDialog和pageSetupDialog 控件，

    并将printDialog、printPreviewDialog和pageSetupDialog控件的Document属性选择printDocument1

 2、相关代码

以下为具体的打印位置代码，要放在“printDocument1_PrintPage”事件中

string rq = DateTime.Now.ToString("yyyy-MM-dd");
                    int num1 = 200;
                    //标签文字开始X点
                    int x0 = 5;
                    int x1 = 100;
                    int x2 = 250;

                    int y1 = 70;
                    //int y2 = 275;
                    StringFormat stringFormat = new StringFormat();
                    stringFormat.Alignment = StringAlignment.Center;
                    stringFormat.LineAlignment = StringAlignment.Center;
                    Pen pen = new Pen(Color.Black, 1f);
                    Font font = new Font("黑体", 18f, FontStyle.Bold);
                    Font font2 = new Font("宋体", 13f, FontStyle.Bold);
                    Brush black = Brushes.Black;
                    //打印SMP文件编号 
                    e.Graphics.DrawString(smpName, font2, black, 80, 0);
                    //创建黑色笔。   
                    Pen blackPen = new Pen(Color.Black, 1);
                    // 创建矩形.
                    Rectangle rect = new Rectangle(0, 18, 280, 331);
                    // 绘制到屏幕上。
                    e.Graphics.DrawRectangle(blackPen, rect);
                    e.Graphics.DrawString(" 物料  产品  标签", font, black, 15, 30);
                    /////////打印勾选用的方框
                    rect = new Rectangle(83, 32, 20, 20);
                    // 绘制到屏幕上。
                    e.Graphics.DrawRectangle(blackPen, rect);
                    rect = new Rectangle(163, 32, 20, 20);
                    // 绘制到屏幕上。
                    e.Graphics.DrawRectangle(blackPen, rect);
                    ////////////

以下为打印按钮的代码
