Converting Printer Code
LPDRVR also lets you convert any printer code to any other code
before it is sent to the printer. It does this by maintaining a 256-
byte table called a character translation table.
Initially code is translated to its original form but, by making
changes to the table, you can set any code to be converted. To
obtain the memory address of the code in the table, make the
necessary BIOS call from an assembly-language program as
follows:
1. Set the AH register to 3.
2. Execute an INT 17H instruction.
The pointer at the beginning of the character translation table is
returned in the ES:BX registers. Each code is offset from the
memory location pointed to by ES:BX by its ASCII value. OFFH
in the table indicates printer code OFFH or indicates that a
string translation is defined for that character. OFFH can then
be changed to redefine the character.
LPDRVR also lets you convert any printer code into a string of
as many as eight codes before it is sent to the printer. You can
define as many as 50 different replacement strings. This is done
by sending the following escape code and code sequence to the
printer driver:
esc wn
code; string
