The Function Codes
REMARKS:
I
When the ESC "E" code is sent to Gemini, all
subsequent characters are printed in the
emphasized print mode. The emphasized
print code is cancelled by sending an ESC
"F" code to the printer - CHR$(27) CHR$(70).
Emphasized printing can only be used with the
normal pica and double·width pica characters
(10 CPI and 5 CPI) and cannot be used with
sub/superscripts. The emphasized print mode
can be combined with double-strike mode.

Print characters with underline.
ESC "-" 1
CHR$(27) CHR$(45) CHR$(1)
When the ESC "." 1 code is sent to the
printer, all subsequent characters are
printed with an underline. The underline mode
is cancelled by the ESC "-" 0 code -
CHR$(27) CHR$(45) CHR$(O).
Print in superscript mode.
ESC "S" 0
CHR$(27) CHR$(83) CHR$(O)
When the ESC "S" 0 command is received by
the printer, the subsequent characters are
printed in superscript mode. While in
superscript, the normal bidirectional print
mode is cancelled and the unidirectional print
mode is invoked. Superscripts may be used
with the italic font and in pica, elite, and
compressed pitches. They may not be used in
double-width print mode or with emphasized
printing mode. Superscripts are always printed
in double-strike. Superscript mode is cancelled
by sending the ESC "T" code CHR$(27)
CHR$(84). This code also cancels the
unidirectional print mode, but does not cancel
the double-strike printing mode.
