Huh?  The format string is always going to be the same: "%s".  I'll assume 
you want to actually want to print the base-10 exponent E symbol and are 
having trouble.
using zcc +ti86 -v -startup=10

   char c = '\x1b';
   putchar (c);

works for me, as does

   const char *s = "1.2\x1b5";
   puts (s);

as does

   const char *s = "1.2\x1b5";
   printf ("%s",s);

The output for the last two is "1.2E5".  Not quite sure what you were 
doing.

Then again, we could give you your first lesson in asm just to show how 
easy it is.

#include "ti86asm.inc"          ;   ROM, RAM, character and key equates
.org            _asm_exec_ram
         ld      hl,str
         call    _puts
         ret
str:    .db     "1.2",Lexponent,"5",0
.end

(again, output is "1.2E5").
