android usb连接打印机，打印各种格式

思路就是，以word为模板，生成.doc文件，转.html,转.pdf文件,转jpg文件。

一。word模板

二。生成需要打印的.doc文件

// 获取模板文件File demoFile = new File(Environment.getExternalStorageDirectory()      + "/aa.doc");// 创建生成的文件File newFile = new File(Environment.getExternalStorageDirectory()      + "/bb.doc");

//给生成的.doc文件赋值

Map<String, String> map = new HashMap<String, String>();map.put("name", name.toString());map.put("sex", sex.toString());map.put("family", family.toString());map.put("birth", birth.toString());map.put("address", address.toString());map.put("idcard",idcard.toString());map.put("InDate", inDate.toString());map.put("jiguan", jiguan.toString());map.put("Phone", Phone.toString());map.put("zhuanzhang", zhuanzhang.toString());map.put("Duanxin", Duanxin.toString());writeDoc(demoFile, newFile, map);
三。通过word转html

public class WordToHtml {   private static final String encoding = "UTF-8";      private static void writeFile(String content, String path) {                 FileOutputStream fos = null;                 BufferedWriter bw = null;                 try {                     File file = new File(path);                     fos = new FileOutputStream(file);                     bw = new BufferedWriter(new OutputStreamWriter(fos,encoding));                     bw.write(content);                 } catch (FileNotFoundException fnfe) {                    fnfe.printStackTrace();                 } catch (IOException ioe) {                     ioe.printStackTrace();                 } finally {                     try {                         if (bw != null)                             bw.close();                         if (fos != null)                             fos.close();                     } catch (IOException ie) {                     }                 }         }          public static void convert2Html(String fileName, String outPutFile)            throws TransformerException, IOException,            ParserConfigurationException {         HWPFDocument wordDocument = new HWPFDocument(new FileInputStream(fileName));//WordToHtmlUtils.loadDoc(new FileInputStream(inputFile));WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter(               DocumentBuilderFactory.newInstance().newDocumentBuilder()                     .newDocument());         File file = new File(fileName);         final String savePath = file.getParentFile().getAbsolutePath();          wordToHtmlConverter.setPicturesManager( new PicturesManager()            {            @Overridepublic String savePicture(byte[] arg0, PictureType arg1,                  String arg2) {               return savePath + "/"+ arg2;            }            } );         wordToHtmlConverter.processDocument(wordDocument);         //save picturesList<Picture> pics=wordDocument.getPicturesTable().getAllPictures();         if(pics!=null){            for(int i=0;i<pics.size();i++){               Picture pic = (Picture)pics.get(i);               System.out.println();               try {                  pic.writeImageContent(new FileOutputStream(                        savePath + "/" + pic.suggestFullFileName()));               } catch (FileNotFoundException e) {                  e.printStackTrace();               }              }         }         Document htmlDocument = wordToHtmlConverter.getDocument();         ByteArrayOutputStream out = new ByteArrayOutputStream();         DOMSource domSource = new DOMSource(htmlDocument);         StreamResult streamResult = new StreamResult(out);         TransformerFactory tf = TransformerFactory.newInstance();         Transformer serializer = tf.newTransformer();         serializer.setOutputProperty(OutputKeys.ENCODING, encoding);         serializer.setOutputProperty(OutputKeys.INDENT, "yes");         serializer.setOutputProperty(OutputKeys.METHOD, "html");         serializer.transform(domSource, streamResult);         out.close();         writeFile(new String(out.toByteArray()), outPutFile);      }}
四。html转转pdf

public boolean createPDF(String rawHTML, String fileName, ContextWrapper context){   File file = new File(fileName);   try{      Document document = new Document();      PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));      document.open();      //  HTML      String htmlText = Jsoup.clean( rawHTML, Whitelist.relaxed() );      InputStream inputStream = new ByteArrayInputStream( htmlText.getBytes() );      //  PDF      XMLWorkerHelper.getInstance().parseXHtml(writer, document,            inputStream, null, Charset.defaultCharset(), new MyFont());      document.close();      return true;   } catch (FileNotFoundException e) {      e.printStackTrace();      return false;   } catch (DocumentException e) {      e.printStackTrace();      return false;   } catch (IOException e) {      e.printStackTrace();      return false;   }}
五。pdf转jpg

public void saveWebviewPic() {   Picture picture = webview.capturePicture();   Bitmap bmp = Bitmap.createBitmap(picture.getWidth(), picture.getHeight(), Bitmap.Config.RGB_565);   Canvas c = new Canvas(bmp);   picture.draw(c);   savePic("/sdcard/html.jpg", bmp, 5);   Toast.makeText(ShowWordActivity.this,"生成图片",Toast.LENGTH_SHORT).show();}// 保存文件public static boolean savePic(String path, Bitmap bmp, int quality) {   if (bmp == null || bmp.isRecycled()) {      return false;   }   File myCaptureFile = new File(path);   try {      BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(myCaptureFile));      if (quality == 1) {// jpg         bmp.compress(Bitmap.CompressFormat.JPEG, 85, bos);      } else if (quality == 2) {// png         bmp.compress(Bitmap.CompressFormat.PNG, 100, bos);      } else if (quality == 3) {// 发微薄用         bmp.compress(Bitmap.CompressFormat.JPEG, 75, bos);      } else if (quality == 5) {// jpg         bmp.compress(Bitmap.CompressFormat.JPEG, 100, bos);      }      try {         bos.flush();         bos.close();         // writeEixf(path);      } catch (IOException e) {         // TODO Auto-generated catch block         e.printStackTrace();      }   } catch (FileNotFoundException e) {      // TODO Auto-generated catch block      e.printStackTrace();   }   return true;}
