 The GUI can automatically find and display printer IP addresses and model names, allowing users to:
 
-- Check printer status.
-- Set the power-off timer.
-- Reset the ink waste counter.
-- Configure the _First TI Received Time_.
-- read and write the EEPROM
+- Check printer status
+- Set the power-off timer
+- Reset the ink waste counter
+- Configure the _First TI Received Time_
+- Read and write the EEPROM
+- Detect the access key (only the *read_key* at the moment)
 
   The *First TI Received Time* in Epson printers typically refers to the timestamp of the first transmission instruction to the printer when it was first set up. This feature tracks when the printer first operated.
