[Notes] □ Whenever receive <10>H<05>H<n> (1 S nS 2) data sequence, will send status.
For example:
ESC * m nL nH dk, d1 = <10>H, d2 = <05>H, d3 = <01>H □ In the command data includes 2 or more
bytes, can not use this command.
For example:
If want to send ESC 3 n to the printer, but before sending the n, DTR ( For the host is DSR)will change to MARK,
