would like to know what the test button of the EpsonFp2Config tool does because I am having problems with a service that if activated interrupts communication with the Epson fiscal printer and I would like to understand what this test does in order to solve the problem. See Image
The operative system is Windows Server 2016 Standard
It does not do a simple ping because in both cases (whether the service is up or down) I can ping.
I have also tried port 9100 and it always gives me true with this command:
Test-NetConnection IP Address -port 9100
I think this test button tries to communicate with the fiscal printer, but how?
