■
During the interval between the sending of the data header and NUL, ASB status and the real time
commands are rendered invalid.
■
When communication with the printer uses XON/XOFF control with serial interface, the XOFF code may
interrupt the “Header to NUL” data string.
■
The information for each function can be identified to other transmission data according to specific data
of the transmission data block. When the header transmitted by the printer is [hex = 37H/decimal =55],
treat NUL [hex = 00H/decimal =0] as a data group and identify it according to the combination of the
header and the identifier.
