Significance of small green sticker put on Printed Application during Biometrics

[fj189]

Dear Members,
we are applying from Pakistan for a spouse visa, all documents are already in the UK for submission to Sheffield.
during biometric appointment, a green sticker has been put by staff on the printed application form. stating name, contact number and gwf number.
any idea if we have to use this form with sticker for sending to Sheffield. as it will need posting from Pakistan to the UK first, incurring cost and time.
any experience of it? can we just take new print out and send from uk?
thanks
