Solution

  • After spend some hours on google i found the solution.

    PrintManager printManager = (PrintManager) this.getSystemService(Context.PRINT_SERVICE);
    String jobName = this.getString(R.string.app_name) + " Document";
    printManager.print(jobName, pda, null);
    
    PrintDocumentAdapter pda = new PrintDocumentAdapter(){
    
        @Override
        public void onWrite(PageRange[] pages, ParcelFileDescriptor destination, CancellationSignal cancellationSignal, WriteResultCallback callback){
            InputStream input = null;
            OutputStream output = null;
    
            try {
    
                input = new FileInputStream(file to print);
                output = new FileOutputStream(destination.getFileDescriptor());
    
                byte[] buf = new byte[1024];
                int bytesRead;
    
                while ((bytesRead = input.read(buf)) > 0) {
                     output.write(buf, 0, bytesRead);
                }
    
                callback.onWriteFinished(new PageRange[]{PageRange.ALL_PAGES});
    
            } catch (FileNotFoundException ee){
                //Catch exception
            } catch (Exception e) {
                //Catch exception
            } finally {
                try {
                    input.close();
                    output.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    
        @Override
        public void onLayout(PrintAttributes oldAttributes, PrintAttributes newAttributes, CancellationSignal cancellationSignal, LayoutResultCallback callback, Bundle extras){
    
            if (cancellationSignal.isCanceled()) {
                callback.onLayoutCancelled();
                return;
            }
    
    
            PrintDocumentInfo pdi = new PrintDocumentInfo.Builder("Name of file").setContentType(PrintDocumentInfo.CONTENT_TYPE_DOCUMENT).build();
    
            callback.onLayoutFinished(pdi, true);
        }
    };
