using BarcodeLib; using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace PrinterTool { public partial class Form1 : Form { public Form1() { InitializeComponent(); } #region 小标签打印需要的参数 string barcode_sub01 = ""; #endregion /// <summary> /// 生成条形码 /// </summary> /// <param name="content">内容</param> /// <returns></returns> public static Image GenerateBarCodeBitmap_sub02(string content, int width = 200, int height = 40) { using (var barcode = new Barcode() { IncludeLabel = false, Alignment = AlignmentPositions.CENTER, Width = width, Height = height, RotateFlipType = RotateFlipType.RotateNoneFlipNone, BackColor = Color.White, ForeColor = Color.Black, LabelPosition = BarcodeLib.LabelPositions.BOTTOMCENTER, }) { return barcode.Encode(TYPE.CODE128B, content); } } private void printDocument5_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e) { printDocument5.DefaultPageSettings.Margins.Top = 0; printDocument5.DefaultPageSettings.Margins.Bottom = 0; printDocument5.DefaultPageSettings.Margins.Left = 0; printDocument5.DefaultPageSettings.Margins.Right = 0; //下面这个也设成高质量 e.Graphics.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality; //下面这个设成High e.Graphics.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic; e.HasMorePages = false; string str = ""; //下面这个也设成高质量 e.Graphics.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality; //下面这个设成High e.Graphics.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic; e.HasMorePages = false; Font titleFont = new Font("黑体", 16, System.Drawing.FontStyle.Bold);//标题字体 Font titleFont2 = new Font("黑体", 14, System.Drawing.FontStyle.Bold);//标题字体 Font fntTxt = new Font("黑体", 12, System.Drawing.FontStyle.Regular);//正文文字 Font fntTxt1 = new Font("黑体", 10, System.Drawing.FontStyle.Regular);//正文文字 System.Drawing.Brush brush = new SolidBrush(System.Drawing.Color.Black);//画刷 System.Drawing.Pen pen = new System.Drawing.Pen(System.Drawing.Color.Black);//线条颜色 try { printDocument5.DefaultPageSettings.PaperSize.Width = 299;//请注意，这里是单位：（百分之一英寸） printDocument5.DefaultPageSettings.PaperSize.Height = 100;//请注意，这里是单位：（百分之一英寸） e.PageSettings.PaperSize.Width = 299;//请注意，这里是单位：（百分之一英寸） e.PageSettings.PaperSize.Height = 100;//请注意，这里是单位：（百分之一英寸） Image barcode = null; barcode = GenerateBarCodeBitmap_sub02($"{barcode_sub01}", 220, 50); e.Graphics.DrawImage(barcode, new System.Drawing.Point(60, 4)); e.Graphics.DrawString($"{barcode_sub01}", fntTxt, brush, new System.Drawing.Point(26, 58)); } catch (Exception ee) { MessageBox.Show(ee.Message); } } private void button1_Click(object sender, EventArgs e) { printDocument5.PrinterSettings.PrinterName = "Gprinter GP-3100TU";//打印机名字//如果不指定，就是默认打印机 barcode_sub01 = "1099009900"; printDocument5.Print(); } } }
