Hi abhi56 - I don't have an answer to your direct question. However, Yansa Labs offers a QR/Barcode Generator app that can expose QR Codes in any ServiceNow interface, and also allows downloading that QR Code. If you're still stuck, this could meet your requirement. The links below may be helpful. Feel free to reach out to me at ben@yansalabs.com with any questions!
