range listed for the character set, a character from a SBCS may print. The
following double-byte character sets are supported by the 6820 Printer.

Multi-Byte Character Sets
DBCS and SBCS 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 codepage currently selected are used for render-
ing 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. Other-
wise, for character codes above 128, the character code from the selected
SBCS is printed. NFT00950.MOD (BIG 5 DBCS) does not allow the
MBCS mode. For this character set, only control codes from 0–31 are
treated as single byte characters when they are not proceeded by a lead-in
byte. All escape sequence character strings are treated as SBCS.
Codepage Selection
Multiple codepages can be present in printer font memory at one time.
One SBCS and one DBCS codepage can be selected as the active code-
pages at any time for MBCS mode. The active codepage can be changed at
any time by substituting the appropriate value into
n1 and n2 from the
International Character Sets table on the next page.

where n0 is 255, n1 is the high byte of codepage to select, and n2 is the
low byte of codepage to select.
