C# 操作打印机

获取当前设置能使用的打印机：

foreach (string sPrint in PrinterSettings.InstalledPrinters)//获取所有打印机名称
            {
                prints.Add(sPrint);
            }

获取打印机下的纸盒：

 PrinterSettings ps = new PrinterSettings();
            ps.PrinterName = printName;
            for (int i = 0; i < ps.PaperSources.Count; i++)
            {
                sources.Add(ps.PaperSources[i].SourceName);
            }

打印图片方法：

private static void PicturePrintDocument_PrintPage(object sender, PrintPageEventArgs e)
        {
            FileStream fs = File.OpenRead(filePath);
            int filelength = 0;
            filelength = (int)fs.Length; //获得文件长度 
            Byte[] image = new Byte[filelength]; //建立一个字节数组 
            fs.Read(image, 0, filelength); //按字节流读取 
            Image result = Image.FromStream(fs);
            fs.Close();
            e.Graphics.DrawImage(result, 0, 0);  //img大小
            //e.Graphics.DrawString(TicCode, DrawFont, brush, 600, 600); //绘制字符串
            e.HasMorePages = false;
        }

注册打印方法：

using (PrintDocument pd = new PrintDocument()) {
                    pd.PrintPage += PicturePrintDocument_PrintPage; //注册打印事件
                    pd.PrinterSettings.PrinterName = printName;        //打印机选择
                    pd.Print();
                    pd.Dispose();
                }
