When the LSB of

[Notes] This mode can be set independently in standard mode and in page mode.
When this command is used in standard mode, the printer sets the mode for standard mode.
When this command is used in page mode, the printer sets the mode for page mode.
When unidirectional print mode is turned off, bidirectional print mode is automatically turned on.
When page mode is selected, the printer performs unidirectional printing for all data that is to be
collectively printed using FF or ESC FF.
Unidirectional print mode can be turned on when printing double-height characters or graphics or bit
image or two dimension code to ensure that the top and bottom of the printing patterns are aligned.
The settings of this command are effective until ESC @ is executed, the printer is reset, or the power is
turned off.
[Model-dependent variations] None
