C# 使用PrintDocument类打印标签

最近做了一个项目,使用不干胶标签贴在RFID抗金属标签上,那么就会出现标签打印的问题,该如何打印呢?后来经过网上冲浪发现,其实打印标签和打印A4纸的方法一样,只不过就是布局、设置纸张大小的问题。

本文介绍打印机初步配置,以及实现方法。标签主要展示资产基本信息以及二维码。

首先设置打印机纸张大小,纸张高宽度以实际标签为准,设置好后可打印测试页测试一下,以ZDesigner GX430t打印机为例。

C# 使用PrintDocument类打印标签

创建PrintDocument实例,以及配置打印机名称:

/// <summary>
/// 打印
/// </summary>
private void Myprinter()
{
PrintDocument pd = new PrintDocument();
pd.PrintPage += new PrintPageEventHandler(printDocument_PrintA4Page); pd.DefaultPageSettings.PrinterSettings.PrinterName = "ZDesigner GX430t"; //打印机名称
//pd.DefaultPageSettings.Landscape = true; //设置横向打印,不设置默认是纵向的
pd.PrintController = new System.Drawing.Printing.StandardPrintController();
pd.Print();
}

设置页面布局,根据实际需求进行排版

private void printDocument_PrintA4Page(object sender, PrintPageEventArgs e)
{
Font titleFont = new Font("黑体", , System.Drawing.FontStyle.Bold);//标题字体
Font fntTxt = new Font("宋体", , System.Drawing.FontStyle.Regular);//正文文字
Font fntTxt1 = new Font("宋体", , 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
{
e.Graphics.DrawString("标题name", titleFont, brush, new System.Drawing.Point(, )); Point[] points111 = { new Point(, ), new Point(,) };
e.Graphics.DrawLines(pen, points111); e.Graphics.DrawString("资产编号:", fntTxt, brush, new System.Drawing.Point(, ));
e.Graphics.DrawString("", fntTxt, brush, new System.Drawing.Point(, ));
e.Graphics.DrawString("资产序号:", fntTxt, brush, new System.Drawing.Point(, ));
e.Graphics.DrawString("", fntTxt, brush, new System.Drawing.Point(, )); e.Graphics.DrawString("底部name", fntTxt1, brush, new System.Drawing.Point(, )); Bitmap bitmap = CreateQRCode("此处为二维码数据");
e.Graphics.DrawImage(bitmap, new System.Drawing.Point(, )); }
catch (Exception ee)
{
MessageBox.Show(ee.Message);
}
}

二维码生成方法,我这里使用zxing

/// <summary>
/// 二维码方法
/// </summary>
/// <param name="asset"></param>
/// <returns></returns>
public static Bitmap CreateQRCode(string asset)
{
EncodingOptions options = new QrCodeEncodingOptions
{
DisableECI = true,
CharacterSet = "UTF-8", //编码
Width = , //宽度
Height = //高度
};
BarcodeWriter writer = new BarcodeWriter();
writer.Format = BarcodeFormat.QR_CODE;
writer.Options = options;
return writer.Write(asset);
}

效果图:

最后附上源码,里面有zxing.dll

  增加一维码打印

/// <summary>
/// 创建条码方法
/// </summary>
/// <param name="asset"></param>
/// <returns></returns>
public static Bitmap CreateCode(string asset)
{
// 1.设置条形码规格
EncodingOptions options = new EncodingOptions();
options.Height = ; // 必须制定高度、宽度
options.Width = ; // 2.生成条形码图片并保存
BarcodeWriter writer = new BarcodeWriter();
writer.Options = options;
writer.Format = BarcodeFormat.CODE_128; //二维码编码
return writer.Write(asset); // 生成图片
}
