Notes on use
• When you initialize or change the printer settings, the printer is reset to reflect the settings. It may take about
1 minute depending on the network settings or environment. Also, your application may indicate power off
during the time waiting for reset. In that case, wait for about 1 minute, and then reconnect to the printer.
• In areas where Wi-Fi communication is congested, your application may erroneously recognize that
communication is disconnected and indicate power off due to response delay. Also, depending on the
combination with the access point used, Wi-Fi communication performance may be degraded. Both of these
issues may be improved by disabling the Wi-Fi power saving function (Power Save). However, since the
power saving function is disabled, the printer will consume more power. The setting can be changed using
Web Config or TM-P20II Utility.
