An application sending various real time and non-real time  commands to which the printer responds can determine which

Responses to transmit peripheral device status (1B 75) and transmit paper sensor status (1B 76) are non-real time 
responses and will arrive in the order in which they were solicited.

Bar codes
These commands format and print bar codes and are described in order of their hexadecimal codes.
These commands describe operation for 80mm paper. If the printer supports 82.5mm paper, the dot spacing is the same but 
there are 640 printable dots rather than the 576 printable dots on 80mm paper.
