ESC Q 2 Deselect Specific Printer
ESCR
ESCS
Format: ESC 0;2;
Sets only the Color Printer so as not to
accept data from the system unit. The
printer must be initialized by the system or
selected using DCI (Select Printer) to
accept data.
LPRINT CHR$(27);CHR$(81);CHR$(2);
Set All Tabs to Power-On Defaults
Sets all tabs, horizontal and vertical, to the
power-on defaults.
LPRINT CHR$(27);CHR$(82);
Subscript or Superscript Printing
Format: ESC S;n;
ESC S followed by
1
changes the printer to
subscript printing. ESC S followed by 0
changes the printer to superscript printing.
ESC S is canceled by ESC T.
Note: If line feed (LF) codes are issued
while in subscript or superscript
printing, the line feed does not change
the subscript or superscript setting. For
example, if in superscript printing, the
line feed causes the paper to advance to
the superscript position of the next line.
Note: The Color Printer operates only
on the least significant bit of n.
Therefore, any odd-numbered ASCII
decimal value gives the same result as
n= 1, and any even-numbered ASCII
decimal value gives the same result as
n=O.
