• When using the READY/BUSY control, make sure that the printer is in power on mode
before you send the data from the host.
• With communication protocols such as XON/XOFF, STATUS3, STATUS4 or STATUS5,
a receive buffer full error will occur when the received data is more than the receive
buffer size (2.95 MB). Send data that is less than 2.95 MB while monitoring the status
of the printer.
• A parity error will be detected if this error occurs after the reception of ESC+A.
• Specifications are subject to change without notice.
