I would've photoshopped the barcode onto a Covid certificate and then ask to print it...

Isn't barcode on the PDF good enough anyway, to be scanned by a machine (either biological or electronic)? Obviously it's Scamair, so they could've imposed dumb rules like "we need the physical paper"

Yup, that's it. They explicitly weren't allowing scanning off of a screen, as far as I remember. (The code on the screen might be fraudulent, after all – can't do that on paper!)
