快速分步解决方案
因为没有提供代码,所以我在提供的链接的帮助下使它工作,这里是代码:
代码
using System;
using System.Runtime.InteropServices;
using System.Windows;
[StructLayout(LayoutKind.Sequential)]
public struct DOCINFO {
[MarshalAs(UnmanagedType.LPWStr)]
public string pDocName;
[MarshalAs(UnmanagedType.LPWStr)]
public string pOutputFile;
[MarshalAs(UnmanagedType.LPWStr)]
public string pDataType;
}
public class PrintDirect {
[DllImport("winspool.drv", CharSet = CharSet.Unicode, ExactSpelling = false, CallingConvention = CallingConvention.StdCall)]
public static extern long OpenPrinter(string pPrinterName, ref IntPtr phPrinter, int pDefault);
[DllImport("winspool.drv", CharSet = CharSet.Unicode, ExactSpelling = false, CallingConvention = CallingConvention.StdCall)]
public static extern long StartDocPrinter(IntPtr hPrinter, int Level, ref DOCINFO pDocInfo);
[DllImport("winspool.drv", CharSet = CharSet.Unicode, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern long StartPagePrinter(IntPtr hPrinter);
[DllImport("winspool.drv", CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern long WritePrinter(IntPtr hPrinter, string data, int buf, ref int pcWritten);
[DllImport("winspool.drv", CharSet = CharSet.Unicode, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern long EndPagePrinter(IntPtr hPrinter);
[DllImport("winspool.drv", CharSet = CharSet.Unicode, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern long EndDocPrinter(IntPtr hPrinter);
[DllImport("winspool.drv", CharSet = CharSet.Unicode, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern long ClosePrinter(IntPtr hPrinter);
}
private void Print(String printerAddress, String text, String documentName) {
IntPtr printer = new IntPtr();
// A pointer to a value that receives the number of bytes of data that were written to the printer.
int pcWritten = 0;
DOCINFO docInfo = new DOCINFO();
docInfo.pDocName = documentName;
docInfo.pDataType = "RAW";
PrintDirect.OpenPrinter(printerAddress, ref printer, 0);
PrintDirect.StartDocPrinter(printer, 1, ref docInfo);
PrintDirect.StartPagePrinter(printer);
try {
PrintDirect.WritePrinter(printer, text, text.Length, ref pcWritten);
} catch (Exception e) {
Console.WriteLine(e.Message);
}
PrintDirect.EndPagePrinter(printer);
PrintDirect.EndDocPrinter(printer);
PrintDirect.ClosePrinter(printer);
}
用法
String printerAddress = "\\\\ComputerName\\PrinterName";
String documentName = "My document";
String documentText = "This is an example of printing directly to a printer.";
this.Print(printerAddress, documentText, documentName);
