I am applying for Teir-2 visa next week ( entry clearance). I got offer letter from my employer in soft copy ( pdf format). Now will home office consider this document as original copy, as I am gonna print it out and submit. I saw in guideline, documents must be original. But I am not sure such whether this type document will be original or will be regarded as copy.
I am sure my question is not about rules, but I have been hurted several times by HO in past, so just wanted to make sure everything is perfect this time.

Regards
