ESC = n selects the device to which the host computer sends data, based on the value of n as follows:
Bit Off/On Hex Decimal Function
Off 00 0 Printer disabled
0
On 01 1 Printer enabled
1-7 - - - Undefined
When the LSB (least significant bit) of n is 1, the printer is enabled; when it is 0, the printer is disabled.
When the printer is disabled, it ignores all received data with the exception of DLE ENQ 1 and DLE ENQ 2.
The default setting is n. If ASB is enabled when the printer is disabled by ESC =, the printer transmits a 4-byte
status message whenever the status changes.

ESC * m nL nH d1 ... dk selects a bit-image mode using m for the number of dots specified by (nL +
nH×256). Set a bit to 1 to print a dot, or set a bit to 0 to not print a dot. d indicates the bit image data. The
modes selectable by m are as follows:

ESC v
Transmit paper sensor status
Format: ASCII ESC v
Decimal 27 118
Hex 1B 76
ESC v transmits the status of a paper sensor as 1 byte of data. This command allows the host to obtain the
near-end or paper-out status for each line. GS r 1 can also be used to check the status. GS r is recommended for
