I need to print line by line in a thermal printer. line breaking at %n I would like to persist the string pattern, while printing.. I m not well versed with printer api and graphic 2d api.. I need to fix this 1 hour time.. Would appreciate a quick answer.. Thanks in advance My String format is like this:

String printStat = 
                        "              *****                  %n"
                      + "       W*** OF ** AND *****        %n"
                      + "      4/400 kfjkasjfdkas ajdksa        %n"
                      + "  aksdka ajke ajeklaje  kajke ka  a   %n"
                      + " Date: "+now.get(Calendar.DAY_OF_MONTH)+"/"+(now.get(Calendar.MONTH)+1)+"/"+now.get(Calendar.YEAR)+"             Time: "+now.get(Calendar.HOUR_OF_DAY)+":"+now.get(Calendar.MINUTE)+"%n"
                      + "--------------------------------------%n"
                      + "    Name            Qty     Price    %n"
                      + "--------------------------------------%n";
