What country are you from ? (Or what country did you complete your education in ?)
I obviously haven't checked the document requirements for every country, but I've just checked a handful of countries, and for all of them there are only 2 options for transcripts:
"Arrange for the documents to be sent directly to WES by the university or autonomous college responsible for conducting the examinations."
or
"If the document is given to you to forward to WES, it must be attested & dated and placed in an official sealed envelope that is signed or stamped across the back flap by the appropriate authentication officer at the institution that conducted the examination. If the envelope has been opened or there is no stamp or signature across the back flap, the document will not be accepted by WES."
Sending in a transcript that you've printed yourself is not an option.
