Graphic Chek Code
GRAPHIC CHEK CODE specifies the replacement character to print in place of
any unprintable character that is received from the host. The character becomes
the printer default when:
The printer is powered off and then powered on.
An SGEA command specifies to use the operator panel default.
The "GRAPHIC CHEK ERR" option is disabled.
LAC Option
The LAC OPTION allows the host system to load alternate character images into
the printer. This may be used for designing graphics, bar codes, and charts, or for
printing in foreign languages.
ENABLE prints the LAC character as defined.
DISABLE ignores the LAC definition from the host and prints from the
currently selected character set.
Set Text Orientn
SET TEXT ORIENTN specifies the direction in which characters are printed on
the page. This allows the printer to print languages that are printed right to left
instead of left to right.
CONTROL BY HOST
LEFT TO RIGHT
RIGHT TO LEFT
Host Override
HOST OVERRIDE determines whether the printer accepts certain commands
sent by the host, or continues to use the current operator panel settings. The
following host commands are ignored when HOST OVERRIDE is enabled: line
length, forms length, lines per inch (LPI), characters per inch (CPI), print quality,
and text orientation (i.e. left to right). When HOST OVERRIDE is enabled, these
settings retain their operator panel settings.
