i'm trying to print out some text with my datamini printer.i want to print full horizontal underline.firstly i'm following this guide from blue bamboo(though its different company but m not getting guide of datamini): http://www.londatiga.net/downloads/P25_Development_Guide_V3.9(2012-12-31).pdf

and secondly i've been trying with these:

        String test2="sometext";
        byte[] arrayOfByte1 = { 0x27, 0x33, 0x00 };
        byte[] format = { 0x27, 0x33, 0x00 };

        format[2] = ((byte)(0x80 | arrayOfByte1[2]));

        mmOutputStream.write(format);
        mmOutputStream.write(test2.getBytes(),0,test2.getBytes().length);

which i pulled out from Format text in bluetooth printer
