C#（Winform）实现条码打印

电脑上安装了39条码字体：C39HrP24DlTt

先看下控件界面截图

转换条码字体

        private void button1_Click(object sender, EventArgs e)
        {
            Bitmap b1 = new Bitmap(Convert.ToInt32(textBox2.Text), Convert.ToInt32 ( textBox3.Text));
            Graphics g1 = Graphics.FromImage(b1);
            Font font1 = new Font("C39HrP24DlTt", Convert.ToInt32(textBox4.Text));
            g1.DrawString(textBox1.Text.ToString(), font1, Brushes.Black, new PointF(Convert.ToInt32(textBox5.Text), Convert.ToInt32(textBox6.Text)));
            pictureBox1.BackgroundImage = b1;
            pictureBox1.BackgroundImageLayout = ImageLayout.Zoom;
        }

pageSetupDialog1、printDialog1、printPreviewDialog1的document属性都选择为printDocument1

给printDocument1添加一个PrintPage事件printDocument1_PrintPage

打印设置

        private void button2_Click(object sender, EventArgs e)
        {
            this.pageSetupDialog1.ShowDialog(); 

        }

打印预览

        private void button3_Click(object sender, EventArgs e)
        {
            this.printPreviewDialog1.ShowDialog(); 

        }

打印

        private void button4_Click(object sender, EventArgs e)
        {
            if (this.printDialog1.ShowDialog() == DialogResult.OK)
            {
                this.printDocument1.Print();
            }
        }

打印内容的设置

        private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            //打印内容 为 整个Form
            //Image myFormImage;
            //myFormImage = new Bitmap(this.Width, this.Height);
            //Graphics g = Graphics.FromImage(myFormImage);
            //g.CopyFromScreen(this.Location.X, this.Location.Y, 0, 0, this.Size);
            //e.Graphics.DrawImage(myFormImage, 0, 0);

            //打印内容 为 局部的 this.groupBox1
            Bitmap _NewBitmap = new Bitmap(groupBox1.Width, groupBox1.Height);
            groupBox1.DrawToBitmap(_NewBitmap, new Rectangle(0, 0, _NewBitmap.Width, _NewBitmap.Height));
            e.Graphics.DrawImage(_NewBitmap, 0, 0, _NewBitmap.Width, _NewBitmap.Height); 

            //打印内容 为 自定义文本内容 
            /*Font font = new Font("宋体", 12);
            Brush bru = Brushes.Blue; 
            for (int i = 1; i <= 5; i++)
            {
                e.Graphics.DrawString("Hello world ", font, bru, i*20, i*20);
            }*/
        }

public Form1()

        public Form1()
        {
            InitializeComponent();
            this.printDocument1.OriginAtMargins = true;//启用页边距
              this.pageSetupDialog1.EnableMetric = true; //以毫米为单位
         }

没有做异常处理，比如没有启动打印服务的情况下，程序会不友好地报错。

转成39条码字体，支持的字符有
A-Z，26个字母，不分大小写，都表示成大写；
0-9，10个数字；
+-*/%$.，7个符号；
space，空格。
