When viewing the image of any record, one should ask “is this an image of the original image or is it something else?” In the case of this 1779/1780 set of marriages, the typed nature of the document indicates it was created sometime after the fact, probably from transcribing original records. Clues that what you are looking at was created later or copied later, includes: handwriting/ink that is too consistent from entry to entry, signatures that are all the same, typed materials from the early 19th century, etc.
Transcriptions are not bad and not necessarily incorrect. Any of them that were created manually were created by humans and can contain the occasional error.
