{
putc(Array[i]);
i++;
}

YES but NOT using printf....
RS-232 frames,by definition, each character with a start and stop bit.
and the UART hardware capability of the pic is oriented to this standard.

what you ask for ...

You are using a legacy PIC with significant architectural limitations, forcing the PIC to consume a large amount of RAM within it's very limited (early 1980s style) RAM banking architecture.
