distance of communication should be within 10 meters, otherwise the printer doesn’t
print or prints rubbish codes.
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.
