Hi,

Thank for your code.
I managed to find the cause.
Those using the "control" font had
to be special command that we can find
inside the printer manual, else it is ignore.

Those using ??? are ESC/POS command for the
printer.

FYI, ??/? and ??? not working well with each other.
I still had problem using them to solve my printer
problem.
