No information is being read from the USB printer on Linux

[konasweik]

I can print labels, but I could not query the situation.

TSPLConnectionClient tsplConnectionClient = new USBConnectionClient((short) 4611);
tsplConnectionClient.addDataListener(new DataListener() {..}
tsplConnectionClient.init();
tsplConnectionClient.connect();
tsplConnectionClient.send(TSPLStatusPollCommands.STATUS.getCommand() + LF);

The printer device has been authorized. MODE="0666"
What I'm doing wrong?

I wonder if that is due to the additional LF in the send command ..

Usually it is not needed as the getCommand() already adds that https://github.com/fintrace/tspl2-driver/blob/master/src/main/java/org/fintrace/core/drivers/tspl/commands/status/TSPLStatusPollCommands.java#L193
So, This is tsplConnectionClient.send(TSPLStatusPollCommands.STATUS.getCommand()); sufficient.

besides that wonder if you recieve anything on to messageSendFailed of DataListener (https://github.com/fintrace/tspl2-driver/blob/master/src/main/java/org/fintrace/core/drivers/tspl/listeners/DataListener.java#L54)

I added LF command it as a reason why it didn't work :) Not working is not related to this.

I added output to the events;
tsplConnectionClient.addDataListener(new DataListener().messageSent:�!?
When I review the output of the MessageSent, messageReceived and messageSendFailed events, I get the MessageSent event.
