我想将数据发送到 LPT1 上的打印机,我正在尝试这样,但我的 CreateFile 返回 -1(系统找不到指定的文件。来自 HRESULT:0x80070002 的异常)。如何打开LPT1端口并将数据发送到?我在 XP 上尝试这个,然后在 win7 64 位中尝试,因为从我读过的内容来看,在 win7 64 位中使用 LPT 有点问题,或者我应该说 64 位问题:)

PS:由于这是我今年的第一篇文章:祝大家新年快乐。

您可以尝试以下方法。适用于文本模式。

TEST         LPT1:                  Spooled  Microsoft XPS Document Writer
The command completed successfully.

这是代码

using System;
using System.IO;

namespace SimplePrinting
{
    /// <summary>
    /// Summary description for Class1.
    /// </summary>
    class SimplePrinting
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main(string[] args)
        {
            string printingTaskFileName = Path.GetTempFileName(); // file in %temp%

            System.IO.FileStream printingTaskFile;
            System.IO.StreamWriter printingTaskStream;

            printingTaskFile = new System.IO.FileStream(printingTaskFileName, FileMode.Append);
            printingTaskStream = new System.IO.StreamWriter(printingTaskFile, System.Text.Encoding.Default);

            printingTaskStream.Write("some content here");
            printingTaskStream.Flush();
            printingTaskStream.Close();

            File.Copy(printingTaskFileName, @"\\127.0.0.1\TEST", true); // also can be \\127.0.0.1\PNT5 or smth like that
            File.Delete(printingTaskFileName);
        }
    }
}
