ESC {
Function:
Turn upside-down printing mode on/off
Code ASCII: ESC { n
Code HEX: 0x1B 0x7B n
Range:
0 ≤ n ≤ 255
Default: n = 0
Description: In standard mode, turns upside-down printing mode on or off.
• When the LSB of n is 0, upside-down printing mode is turned off.
• When the LSB of n is 1, upside-down printing mode is turned on.
Notes:
• When standard mode is selected, this command is enabled only when
processed at the beginning of the line.
• The upside-down printing mode is effective for all data in standard
mode.
• The upside-down printing mode has no effect in page mode. If this
command is processed in page mode, an internal flag is activated, and
this flag is enabled when the printer returns to standard mode.
• The settings of this command are effective until ESC @ is executed, the
printer is reset, or the power is turned off.
• When upside-down printing 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.
