4.1 About wireless communication

4.1.1 For Application developing

The TM-P60 uses wireless comunication technology; therefore temporary communication
breaks may occur when you move or are in an outside environment. When you develop
application software using wireless communication, you should consider this.
We recommend you confirm whether or not the printer printed after every print data
transmission unit. Detection of communication errors and recovering from such errors are also
important. Data communication without confirmation of printing and detetection of
communication errors may cause data loss.
To ensure heghly reliable data communication, we recommend the use of the status
confirmation function of our genuine OPOS, or Windows Printer Driver (APD).

4.1.2 For Radio field intensity

Wireless communication is related to radio field intensity. The TM-P60 has a function,"Radio
Field Intensity Check Mode" (page 3-5), to confirm the current radio field intensity. This mode
shows the current radio field intensity to the operator.
The function can't be executed from any drivers (OPOS, Advanced Printer Driver) or ESC/POS
commands.
