Below the barcode is there a number or some combination of numbers and letters? If so, write them down on a separate peice of paper. Go to google and download the 3 of 9 font (typical barcode font) and install it. Then open up MS WORD and type in the number/letter combination but change the last number or letter to the next one in rotation so like if it is 12345 make the new one 12346. Highlight it and change your font to 3 of 9, now you have a new barcode for the ink, tape it on and see if that works, JUST MY $.02
Good luck
