我在移动应用程序中，我想打印到明星蓝牙打印机。Star 有一个 SDK，其中包含一个名为 StarIOPort3.1.jar 的 .jar 库，它负责打开/关闭打印机端口、获取状态以及将打印作业发送到打印机。

Star SDK 也有一个演示应用程序，具有打印机的所有功能。

在这个演示应用程序中，打印功能如下

    public void ShowTextFormating(View view)
    {
        EditText portNameField = (EditText)findViewById(R.id.editText_PortName);
        portName = portNameField.getText().toString();

    CheckBox portSettingsCheckBox = (CheckBox)findViewById(R.id.checkBox_PortablePrinter);
    portSettings = "";
    if(portSettingsCheckBox.isChecked() == true)
    {
        portSettings = "mini";
    }

    if(portSettingsCheckBox.isChecked() == true)
    {
        Intent myIntent = new Intent(this, textFormatingMiniActivity.class);
        startActivityFromChild(this, myIntent, 0);
    }
    else
    {
        Intent myIntent = new Intent(this, textFormatingActivity.class);
        startActivityFromChild(this, myIntent, 0);
    }
}

如果选中便携式打印机复选框，则调用 textFormatingMiniActivity.class。

textFormatingMiniActivity.class 如下

package com.StarMicronics.StarIOSDK;

import com.StarMicronics.StarIOSDK.PrinterFunctions.Alignment;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.*;

public class textFormatingMiniActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mini_textformating);

        Spinner spinner_height = (Spinner)findViewById(R.id.spinner_height);
        SpinnerAdapter ad = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, new String[] {"1", "2", "3", "4", "5", "6", "7", "8"});
        spinner_height.setAdapter(ad);

        Spinner spinner_width = (Spinner)findViewById(R.id.spinner_width);
        ad = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, new String[] {"1", "2", "3", "4", "5", "6", "7", "8"});
        spinner_width.setAdapter(ad);

        Spinner spinner_alignment = (Spinner)findViewById(R.id.spinner_alignment);
        ad = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, new String[] {"Left", "Center", "Right"});
        spinner_alignment.setAdapter(ad);
    }

    public void PrintText(View view)
    {
        String portName = StarIOSDKActivity.getPortName();
        String portSettings = StarIOSDKActivity.getPortSettings();

        CheckBox checkbox_underline = (CheckBox)findViewById(R.id.checkbox_underline);
        boolean underline = checkbox_underline.isChecked();

        CheckBox checkbox_emphasized = (CheckBox)findViewById(R.id.checkbox_emphasized);
        boolean emphasized = checkbox_emphasized.isChecked();

        CheckBox checkbox_upsidedown = (CheckBox)findViewById(R.id.chechbox_upsidedown);
        boolean upsidedown = checkbox_upsidedown.isChecked();

        CheckBox checkbox_invertColor = (CheckBox)findViewById(R.id.checkbox_invertcolor);
        boolean invertColor = checkbox_invertColor.isChecked();

        Spinner spinner_height = (Spinner)findViewById(R.id.spinner_height);
        byte height = (byte) spinner_height.getSelectedItemPosition();

        Spinner spinner_width = (Spinner)findViewById(R.id.spinner_width);
        byte width = (byte) spinner_width.getSelectedItemPosition();


        EditText edittext_leftmargin = (EditText)findViewById(R.id.edittext_leftmargin);
        int leftMargin = 0;
        try
        {
            leftMargin = Integer.parseInt(edittext_leftmargin.getText().toString());
        }
        catch(Exception e)
        {
            leftMargin = 0;
        }

        Spinner spinner_alignment = (Spinner)findViewById(R.id.spinner_alignment);
        PrinterFunctions.Alignment alignment = PrinterFunctions.Alignment.Left;
        switch(spinner_alignment.getSelectedItemPosition())
        {
        case 0:
            alignment = Alignment.Left;
            break;
        case 1:
            alignment = Alignment.Center;
            break;
        case 2:
            alignment = Alignment.Right;
        }

        EditText edittext_texttoprint = (EditText)findViewById(R.id.editText_TextToPrint);
        byte[] texttoprint = edittext_texttoprint.getText().toString().getBytes();

        MiniPrinterFunctions.PrintText(this, portName, portSettings, underline, emphasized, upsidedown, invertColor, height, width, leftMargin, alignment, texttoprint);
    }

这是我的问题：

如何从 jquery 调用 MiniPrinterFunctions.PrintText 因为我的应用程序是用 Jquery 编写的...

有没有其他方法可以使用上面的代码从 jquery 打印到这台打印机

请帮忙

提前谢谢
