1-16 Command Descriptions Rev. A

ESC G n turns double-strike mode on or off. When the LSB (least significant bit) of n is 1, double-

strike mode is turned on; when it is 0, double-strike mode is turned off. The default setting is n=0.

Double-strike and emphasized printing appear the same. This command is enabled only in standard

mode. If this command is entered in page mode, an internal flag is activated and the command is

enabled when the printer returns to standard mode.

ESC { n

[Format] ASCII ESC { n

Hex 1B 7B n

Decimal 27 123 n

[Range] 0 ≤ n ≤ 255

ESC { n turns upside-down printing mode on or off. When the LSB (least significant bit) of n is 1,

upside-down printing mode is turned on; when it is 0, upside-down printing mode is turned off. The

default setting is n=0. When upside-down mode is turned on, the printer prints 180°-rotated

characters from right to left. The line printing order is not reversed; therefore be careful of the order

of the data transmitted. In standard mode, this command is enabled only when input at the

beginning of a line. In page mode, the print direction is set with ESC T, an internal flag is activated,

and this command is enabled when the printer returns to standard mode.

PRINT #1, "AAAAA"; CHR$(&HA); BBBBB ← Double-strike mode turned off

PRINT #1, CHR$(&H1B);"G";CHR$(0); ← Canc el

PRINT #1, "BBBBB"; CHR$(&HA);
