What is the maximum allowed current [in mA] for the wires of an LPT cable? The cable is 1.8 meters long.
Maximum current would depend on the gauge, type, and quality of wire used to make the cable.
Not all cables are made the same... some are higher quality and provide better transmission distances while others are generic, cheap, and won't handle the same load.
If you're an electronics person... it's kind of like comparing copper to aluminum... so the answer would be... it really depends on your cable...
