Notes on use Time required until printing starts If the host computer and the printer are not connected on a continuous basis but rather connected every time the printer starts printing, some time may be needed for the printer to actually start printing after the host computer commands printing. This pause is the time required for processing the connection between the host computer and the printer. After opening the port, leave an interval of 300 msec or more before sending data to the port. Timing to shut the connection off If a connection between the host computer and the printer is shut off while the printer is offline, it may not be re-established.
In this case, first clear the printer offline causes, and then try to re-establish the connection. Multi-tone printing When performing multi-tone printing over Bluetooth , the print speed may fluctuate or intermittent printing may occur due to data transfer conditions, also the print shade may change or white lines may occur. Interference from Wi-Fi 2.4 GHz Wi-Fi may interfere with Bluetooth communication. Using the optional Wireless LAN cable set (OT- WLxx) with 2.4 GHz may disrupt Bluetooth communication or printing. 5 GHz Wi-Fi is recommended when using Wi-Fi with Bluetooth . Notes when communicating with Android devices • The printer cannot connect to Android 2.3 and 2.3.2.
• When communicating with Android 2.3.3 or later versions, communicate through an insecure connection. Notes when communicating with iOS devices 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. 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 Solution Do not send data to the printer if the printer is not ready to print.
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. For developers using the SDK from Epson, see the SDK User's Manual provided. 136
