*       Build up a table with the whole ASCII 8-Bit character set.  This table
* is used to translate 8-Bit characters to 7-Bit characters if the printer is 
* doing character fallback translation.  This only exists for to keep the
* printer code equivalent to that in the old LP11 interface.  Any modern
* printer that is likely to be controlled by LRDRIVER should be capable of
* deaing with 8-Bit characters.
