Chapter 3 Notes on Usage Notes on Usage Disconnection Timing Even when data communication has been completed from the host computer's application, data may remain in the Bluetooth module's buffer. Since data in the buffer may be lost when a connection is disconnected, use a status check and so on to confirm that transmitted data has definitely been printed before disconnecting. Notes on Using the Printer with an iOS Device Print data deletion and Bluetooth disconnections occur Situation Depending on the specifications of the iOS device, print data sent to the printer may be deleted. When this occurs, the Bluetooth connection between the printer and the iOS device is disconnected. 3 Conditions This occurs when the printer is not ready to print, and 64 KB or more of print data is sent to the printer.  When the roll paper cover is open  When the paper is out  When waiting for printed labels to detach (Peeler models only) Solution Do not send data to the printer if the printer is not ready to print. For developers using the SDK from Epson, see the User's Manual - Chapter 3 Programming Guide - "Printing After Checking the Printer Status". Since Bluetooth is disconnected when this occurs, if the auto reconnect feature is not enabled, you need to reconnect from the Bluetooth settings screen on the iOS device. When using the SDK from Epson, this connection process is not necessary. 15
