Description
This command is used to obtain the printer status. An inquiry request is
solicited by sending an <ESC> (ASCII 27, escape character) as the
beginning control character to the printer. It can be sent any time, even
in the event of printer error. One byte character is returned, of which one
bit is used to flag the printer’s current readiness status. If 0 is returned,
the printer is ready to print labels.
