Esc Pos how to know if print job is ended

1.8k views Asked by At

Is there any method to understand if a ESC POS print job via serial cable is ended? I know there is some status query to send to printer, but I could not find any for understand if the print job is end (or print buffer is empty).

You could check CTS signal before sending the command, and then return true from your method if the command was executed
