QR Simplifeid Invoice Phase2

Is there an issue with printing the QR code for Phase One on simplified invoices? Sometimes, I need to review the invoice before sending it, and there is no internet in the branches, so I want to send it from the head office. However, I want to print a barcode on the invoice. Can I initially print the QR code for Phase One until the invoice is sent to the authority?

Are there any penalties for doing so?
