.NET code发送ZPL到Zebra打印机

问题描述：

有没有办法送ZPL（Zebra的编程语言），以一台打印机在.NET？

Is there a way to send ZPL (Zebra Programming Language) to a printer in .NET?

我有code，为此在Delphi中，但它不是pretty的，我宁可不要试图重建它在.NET中，因为它是。

I have the code to do this in Delp but it is not pretty and I would rather not try to recreate it in .NET as it is.

看看这个线程：Print ZPL codeS到Zebra打印机使用PrintDocument类。

具体的OP选择这个功能，从答案的线索：

Specifically the OP pick this function from the answers to the thread:

[DllImport("kernel32.dll", SetLastError = true)]
static extern SafeFileHandle CreateFile(string lpFileName, FileAccess dwDesiredAccess,
uint dwShareMode, IntPtr lpSecurityAttributes, FileMode dwCreationDisposition,
uint dwFlagsAndAttributes, IntPtr hTemplateFile);

private void Print()
{
    // Command to be sent to the printer
    string command = "^XA^FO10,10,^AO,30,20^FDFDTesting^FS^FO10,30^BY3^BCN,100,Y,N,N^FDTesting^FS^XZ";

    // Create a buffer with the command
    Byte[] buffer = new byte[command.Length];
    buffer = System.Text.Encoding.ASCII.GetBytes(command);
    // Use the CreateFile external func to connect to the LPT1 port
    SafeFileHandle printer = CreateFile("LPT1:", FileAccess.ReadWrite, 0, IntPtr.Zero, FileMode.Open, 0, IntPtr.Zero);
    // Aqui verifico se a impressora é válida
    if (printer.IsInvalid == true)
    {
        return;
    }

    // Open the filestream to the lpt1 port and send the command
    FileStream lpt1 = new FileStream(printer, FileAccess.ReadWrite);
    lpt1.Write(buffer, 0, buffer.Length);
    // Close the FileStream connection
    lpt1.Close();

}
