Status codes are reset when:

• the conditions causing them are removed

• the printer is power cycled (turned off/on)

• the print head is lifted and then lowered to clear a paper jam. 

<ESC><ENQ><1>

 issues a status enquiry that results in response ACK (06 hex) if there are no 

errors, or NAK (15 hex) and a byte indicating an error if one or more sensors report some 
condition. 

All status commands except for the acknowledge marker are immediate. This 

means that these commands bypass the print queue and are answered as soon as they possibly 
can be.
