Connected remotely to the PC in the warehouse to see what is the cause of the error they encountered, as per checking, the cause of the error is that the extraction command in the application commented out, it is because, when fixed other concern in the warehouse the command is temporarily commented out and did not remove. Update the exe on the user side then check the searching of data again, as per checking, it is now OK,
Checked the second PC for fixing the problem, as per testing on this PC, an error is encountered when executing the search button, update the exe on this PC as well then tested the searching of data, as per testing the searching is successful, tested printing of the barcode, as per user, the barcode is printed.
Got feedback that the first PC I fixed is not printing a barcode, check if there are errors, as per the user, there are no errors, checked if another barcode is printing, as per the user it is not, passed the checking to avasia as the problem might be on the printer side.
