 Thank you again Eli
       I got the printer worling fairly well but I still am having
trouble with spacing. I have tried several combinations but had no luck. 
       I am trying to set the spacing for different size fonts, but
cannot get the printer
to take them. the below commands are both decimal and hex.

        n/72 inch paper spacing.
        Name: ESC   A    n 
        Dec.       27   65   n 
        Hex.        1B   41  n

       fprintf(stdprn, "\x1B\x41");
       
        Its the n part of the command that throws me. I have tried %i,
%c, %h .
        
         example:
        fprintf(stdprn, "%i" "SeventySecond");

        The n spacing in decimal goes from 0 to 255.
                Again I would appreciate any help you could give me on
this
   Thank you
       Vince McCarthy.
