In my opinion, it doesn’t make any difference. What makes the difference is the result being updated on your myACCA. The normal timing for updating results is 72 hours. If the portal is updated, you’ll receive an email. After that you should verify by logging into myACCA.
If you still have any queries, its better to contact your local ACCA office.
Printing the results is only a backup in case you have any problems with ACCA’s system not updating your score. I’ve not heard of anyone having this problem. CBEs have been going for years now so I would think ACCA’s systems are good enough to cope.
