[Notes]
· If any of the status items in the table above are enabled, the printer transmits
four-byte status of the printer in case that this status is changed.
· If all status items are disabled, the ASB function is also disabled.
· The following status bytes are transmitted without confirming whether the
host is ready to receive data.
· Since this command is executed after the data is processed in the receive
buffer, there may be a time lag between data reception and status
transmission.
· Even though the printer is disabled by
ESC =,
the four-byte status are transmitted
whenever the status changes.
· The status to be transmitted are as follows:
