unity打印生成之后的条形码（二维码也行）

QR CodeBarcode Scanner and Generator Cross PlatformPro 4.3.unitypackage + LCPrinter.unitypackage (Unity二维码条形码生成工具+unity打印机)

稍微修改了一下里面的脚本改为CodeController。

}

再次修改一下LCPrinterScript

using UnityEngine;
using System.Collections;
using System.Diagnostics;
using System;
using System.IO;
using LCPrinter;
using UnityEngine.UI;public class LCPrinterScript : MonoBehaviour {public StorageScript storageScript;public Texture2D texture2D;public string printerName = "";public int copies = 1;public InputField inputField;public void printSmileButton(){if (storageScript.IsSingleNumber()){storageScript.Status_Color_Text(Color.blue, "入库条码打印成功");Print.PrintTexture(storageScript.PrintQrCreat().EncodeToPNG(), copies, printerName);//Print.PrintTexture(texture2D.EncodeToPNG(), copies, printerName);return;}storageScript.Status_Color_Text(Color.red, "没有有效的打印内容");}public void printByPathButton(){Print.PrintTextureByPath("D:\\pic.png", copies, printerName);//Print.PrintTextureByPath(inputField.text.Trim(), copies, printerName);}
}

调用脚本

/// <summary>/// 打印条码/// </summary>public Texture2D PrintQrCreat(){return e_qrController.EncodeT2D(InputField_Text[1].text);}

就可以使用了。
