Hi, I need to create an application that will detect and handle cash drawer, whether it is attached with POS receipt printer via RJ11-to-RJ45 connector or is directly connected to PC via USB port or RJ11 port.

Hardware specification:
a. TVS receipt printer
b. Posiflex cash drawer

1. Do I need to write a code to detect the connecting ports and then issue a command for opening drawer?
2. Does windows OS will handle the opening of drawer while i print the receipt?
3. Which library is suitable for accessing USB and RJ11 port?

I look forward for some help and guidance.
