最近在学习Android API相关知识，才后知后觉地发现Android带有原生的打印功能。参考了http://www.kuqin.com/shuoit/20140625/340810.html网站资料，把官方的相应代码整理成了个Demo，

/** * 主页面 *  * @description： * @author ldm * @date 2016-4-28 上午9:54:17 */public class MainActivity extends Activity implements OnClickListener {    private Button bitmap_btn;    private Button layout_btn;    private Button html_btn;    private Button off_screen_btn;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initViews();    }    private void initViews() {        this.bitmap_btn = (Button) findViewById(R.id.bitmap_btn);        this.layout_btn = (Button) findViewById(R.id.layout_btn);        this.html_btn = (Button) findViewById(R.id.html_btn);        this.off_screen_btn = (Button) findViewById(R.id.off_screen_btn);        this.bitmap_btn.setOnClickListener(this);        this.layout_btn.setOnClickListener(this);        this.html_btn.setOnClickListener(this);        this.off_screen_btn.setOnClickListener(this);    }    @Override    public void onClick(View v) {        switch (v.getId()) {        case R.id.bitmap_btn:            startIntent(PrintBitmapActivity.class);            break;        case R.id.layout_btn:            startIntent(PrintLyaoutActivity.class);            break;        case R.id.html_btn:            startIntent(PrintHtmlActivity.class);            break;        case R.id.off_screen_btn:            startIntent(PrintHtmlOffScreenActivity.class);            break;        }    }    private void startIntent(Class<?> tagert) {        Intent in = new Intent(this, tagert);        startActivity(in);    }}

/** * Android图片打印 *  * @description * @author ldm * @date 2016-4-27  */public class PrintBitmapActivity extends Activity {    private ImageView mImageView;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.print_bitmap);        mImageView = (ImageView) findViewById(R.id.image);    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        super.onCreateOptionsMenu(menu);        getMenuInflater().inflate(R.menu.print_custom_content, menu);        return true;    }    @Override    public boolean onOptionsItemSelected(MenuItem item) {        if (item.getItemId() == R.id.menu_print) {            print();            return true;        }        return super.onOptionsItemSelected(item);    }    private void print() {        // // bitmap打印工具类。        PrintHelper printHelper = new PrintHelper(this);        /**         * PrintHelper通过setScaleMode()方法设置模式，现在有两种模式         * SCALE_MODE_FIT：这个打印完整的图片，这样打印纸的边缘可能有空白         * SCALE_MODE_FILL：这个填满所有的打印纸，因此图片的边缘可能打印不出来         */        printHelper.setScaleMode(PrintHelper.SCALE_MODE_FIT);        // 获取ImageView这个用于显示图片的控件里的图片        Bitmap bitmap = ((BitmapDrawable) mImageView.getDrawable()).getBitmap();        // 打印图片        printHelper.printBitmap("Print Bitmap", bitmap);    }}
