FT_PCHR()
 Convert printer control codes

 Syntax

       FT_PCHR( <cString> )  ->  <cPrinterFormat>

 Arguments

       <cString> is the representation of the printer control codes in
       text, numeric, hexadecimal, Epson command format, or any combination
       separated by commas.

 Returns

       A character string of printer control codes.

 Description

       This function is useful for allowing the user to enter printer
       control codes in text (enclosed in double quotes), numeric,
       hexadecimal, or Epson commands preceded by a slash and returns
       the printer control code equivalent.

       NOTES"

            separated by commas ("A",27,&1B,/RESET).

         - Hexadecimal must be preceded by an ampersand (&1B).
         - Epson commands, listed below, must be preceded by a forward
            slash (/RESET).
