USTATUS Command 

Sending the 

USTATUS

 command makes unsolicited printer status (sending the printer status information to 

the host computer automatically without being requested for it) valid or invalid.  If the unsolicited status is set 
to ON with the 

USTATUS

 command, the printer sends unsolicited status information to the host computer at 

the time interval set by 

USTATUS TIMED

 command from when the status changes.  On the other hand, the 

DINQUIRE

, 

INQUIRE

 and 

INFO

 commands make the printer send a response only once, just after they are 

received.
