the distance of communication should be within 10 meters, otherwise the printer doesn’t print or prints rubbish codes.
Though printer can work properly in the 0℃~50℃ environment, too high（45℃ ）or too low（ 5℃ ） environment temperature and too high (85 ％ ) or too low (20 ％ ) environment humidity both effect the printing quality.
The printer paper roll with poor quality or stored for too long time also may reduce the printing quality even damage the printer.
Under the black mark detecting mode, the printer requires that the pre-printed black mark is accordant with the printing rule of black mark (please refer to details in Chapter 4.2), otherwise the black mark can not be detected correctly.
Be sure to use up the power of the battery before charge up it, as it can ensure the using life of the battery. The common working life of printer is:the times of  arge/discharge ≥ 300, battery performance will decrease with the charge/discharge times developed.

Notice of Storing

The printer should be placed in such an environment that the temperature is between-20℃ and 60℃, and the relative humidity is between 5% and 95%.
If the printer will be stored for a long time, please be sure to take out the battery, otherwise may damage the battery and printer.
If the printer will be stored for more than three months, battery should be installed and charged on the printer, which in avoid of battery damage of self discharge.
