                MainActivity.mBixolonPrinter.setSingleByteFont(BixolonPrinter.CODE_PAGE_FARSI);
                //i have a file it's name is new2.txt and readContentOfFile is a method which read all of text in new2.txt and at last print data on the paper
                MainActivity.mBixolonPrinter.printText(readContentOfFile(),BixolonPrinter.ALIGNMENT_CENTER,BixolonPrinter.TEXT_ATTRIBUTE_FONT_A,BixolonPrinter.TEXT_SIZE_HORIZONTAL1,true);

            String line;

            while ((line = br.readLine()) != null) {
                text.append(line);
                text.append('\n');
            }
            br.close();

Answer 1

You can use one of the Farsi options available for the Bixolon printer, for example one of the following:

// Farsi option : Mixed
MainActivity.mBixolonPrinter.setFarsiOption(BixolonPrinter.OPT_REORDER_FARSI_MIXED);

// Farsi option : Right to Left
MainActivity.mBixolonPrinter.setFarsiOption(BixolonPrinter.OPT_REORDER_FARSI_RTL);
