If a portable computer connected to a printer with an infrared interface works fine indoors but sporadically outside, what can you do to fix this? (Select two)

Move the printer closer to the computer
Increase the printer's power supply
Block direct sunlight
Use a different printer

The correct answer is: Move the printer closer to the computer

Moving the printer closer to the computer can significantly enhance the reliability of the infrared connection. Infrared communication requires a clear line of sight between the transmitting and receiving devices. By reducing the distance, you minimize the chance of interference and obstacles that may affect the signal strength. In outdoor environments, factors such as air humidity, obstacles, or even sunlight can further weaken signals, hence decreasing the distance can help maintain a more stable connection. In addition, blocking direct sunlight is also an effective strategy. Infrared signals can be disrupted by bright sunlight, which may interfere with the communication between the computer and the printer when used outdoors. Direct sunlight can overpower the infrared signal, causing sporadic connectivity. Implementing measures to shield the devices from sunlight can help maintain a clearer signal, ensuring more reliable performance. These actions address the potential causes of connectivity issues when using infrared interfaces in varying environmental conditions.
