Single-Byte Character Sets

Single-byte character sets (SBCS) are supported for MS-DOS, PL/N,
and Intermec application compatibility. Nft00000.mod is the default
character set (font) for compatibility with the 6820 Nft00437.mod is the
IBM/Microsoft compatible character set for Code Page 437.
Double-Byte Character Sets
Double-byte character (DBCS) sets require two bytes to send to the
printer to define the character to print. The first byte of the character
code sent to the printer is known as a lead-in byte. The second byte of
the character code is known as the trailing byte. Different character sets
have different requirements for the values of both lead-in and trailing
byte. When the lead-in byte does not fall in the range listed for the
character set, a character from a SBCS may print. The following
double-byte character sets are supported by the 6820.

Multi-Byte Character Sets

Double-byte character sets and single-byte character sets can mix when
printing a report. This mixture is referred to as a Multi-Byte Character
Set (MBCS). When a DBCS is selected, the characters from the SBCS
code page currently selected are used for rendering character codes and
control codes from 0 to 127. Codes above 127 (that fall within the range
of lead-in bytes for the selected character set) treat the byte that follows
as a trailing byte for that character set. Otherwise, for character codes
