Discussed with Ms. Mona whose PC I should connect for the barcode, and told to me that it is sir Joselito. Connected remotely to sir Joselito's PC for testing and checking the output of barcode with a new font on his side, when he tried printing, the barcode is not printing, modified the application and remove the changes on the printing, paste the new exe and advise him to test it again, as per checking, the output is now OK, this is confirmed by the user.
