Question

求一个支持芯烨XP-58IIIA USB小票打印机的C#打印demo程序（有满意答案追加50分悬赏！）

买了一台USB口的芯烨XP-58IIIA 热敏小票打印机， 兼容EPSON ESC/POS和Star两种指令模式。不懂得怎样用C#来操作USB口发指令打印小票，希望哪位用过类似打印机的大侠能提供一下demo程序。

Answer 1

/// <summary>
/// 打印
/// </summary>
/// <param name="printerName">安装的打印机名</param>
/// <param name="filePath">打印文件路径</param>
/// <returns>打印结果,true:打印正常，false:打印出错</returns>
public bool Print(string printerName, string filePath)
{
bool result = true;
try
{
//开始打印
streamToPrint = new StreamReader(filePath, System.Text.Encoding.Default);
PrintDocument pd = new PrintDocument();
pd.DefaultPageSettings.Margins.Top = 2;
pd.DefaultPageSettings.Margins.Left = 12;
pd.DefaultPageSettings.PaperSize.Width = 320;
pd.DefaultPageSettings.PaperSize.Height = 5150;

pd.PrinterSettings.PrinterName = printerName;
pd.PrintPage += new PrintPageEventHandler(this.pd_PrintPage);
pd.Print();

}
catch (Exception ex)
{
result = false;
}
finally
{
if (streamToPrint != null)
streamToPrint.Close();
}

以前做过的打印机 也是热敏的
