使用Unity调用打印机的代码如下：

using System;

using System.Diagnostics;

using System.Drawing.Printing;

using System.IO;

using UnityEngine;

namespace LCPrinter

{

public static class Print

{

public static void PrintTexture(byte[] texture2DBytes, int numCopies, string printerName)

{

if (texture2DBytes == null)

{

                UnityEngine.Debug.LogWarning("LCPrinter: Texture is empty.");

return;

}

PrinterSettings printerSettings = new PrinterSettings();

if (printerName == null || printerName.Equals(""))

{

printerName = printerSettings.PrinterName;

                UnityEngine.Debug.Log("LCPrinter: Printing to default printer (" + printerName + ").");

}

string str = string.Concat(new string[]

{

DateTime.Now.Year.ToString(),

"-",

DateTime.Now.Month.ToString(),

"-",

DateTime.Now.Day.ToString(),

"-",

DateTime.Now.Hour.ToString(),

"-",

DateTime.Now.Minute.ToString(),

"-",

DateTime.Now.Second.ToString(),

"-",

DateTime.Now.Millisecond.ToString()

});

string text = (Application.persistentDataPath + "\\LCPrinterFiletmp_" + str + ".png").Replace("/", "\\");

            UnityEngine.Debug.Log("LCPrinter: Temporary Path - " + text);

File.WriteAllBytes(text, texture2DBytes);

            Print.PrintCMD(text, numCopies, printerName);

}

public static void PrintTextureByPath(string path, int numCopies, string printerName)

{

PrinterSettings printerSettings = new PrinterSettings();

if (printerName == null || printerName.Equals(""))

{

printerName = printerSettings.PrinterName;

                UnityEngine.Debug.Log("LCPrinter: Printing to default printer (" + printerName + ").");

}

Print.PrintCMD(path, numCopies, printerName);

}

private static void PrintCMD(string path, int numCopies, string printerName)

{

Process process = new Process();

try

{

for (int i = 0; i < numCopies; i++)

{

process.StartInfo.FileName = "rundll32";

process.StartInfo.Arguments = string.Concat(new string[]

{

"C:\\WINDOWS\\system32\\shimgvw.dll,ImageView_PrintTo \"",

path,

"\" \"",

printerName,

"\""

});

process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

process.StartInfo.UseShellExecute = true;

process.Start();

                }

}

catch (Exception arg)

{

                UnityEngine.Debug.LogWarning("LCPrinter: " + arg);

}

finally

{

process.Close();

                UnityEngine.Debug.Log("LCPrinter: Texture printing.");

}

}

}

}
