33) Automatic transmission of printer status : << GS v NUL >>
Code
*Automatically transmits the status when the printer status changes.
*Once setting is made, it is effective until software is reset, power is set off, or reset
signal is input.
*The commands are stored in the internal receive input buffer and executed
sequentially.
*Status of transmission is one byte and functions are explained below.

34) Registration of NV bit image : << GS T n >>
Code
Registers the bit image print data determined in advance.
*Three patterns can be registered from 0 ~ 2.
*Bit image print data for each pattern can be registered up to the maximum paper
length of 150mm. The exceeding data to the maximum value is neglected.
*The registered data will not be erased by power off/on, input of reset signal, printer
initialization or software reset.
n values assign following justification.
*When registration starts in the middle of a line, whole line is registered.
* When registration ends in the middle of a line, whole line is not registered

35) NV bit image print: << GS P n >>
Code
: [1D] h + [64] h + Dn
Prints the bit image print data registered.
*Selects a pattern to be printed from the registered data (0~2, three patterns) by using
"n" value.
