    Welcome Mr. Dilip. LPT Port is by default absent now for most PCs. If you have used a NET USE command to set LPT1 to the printer and changed the printer port to be the USB Virtual port, it might not work. I am not sure whether you have already used this method.
    Another better option may be to add a true parallel port using a PCI adapter card.
