“What is actually on the back of the BC copy would be necessary to confirm the accuracy of the statement.”
Not really, I want to see the inside of that envelope, too. Disassembled if necessary. If there is ink on the back of the photocopy, there is ink on the inside of that envelope!
And one would think some kind of smudging on the receipt. Ink doesn’t just transfer up and away—it smudges.
Would it matter whether the ink was from a photocopier (toner) or whether it was from a printer (ink cartridge)?
I’m not very knowledgeable about all this stuff.
You’re so full of horsesh*t. You have no idea what you’re talking about. Just because there is toner transfer on the back of the long-form doesn’t mean there has to also be toner transfer to the envelope or smudging on the receipt.
As I’ve said, numerous times now, it only takes a second for the toner to dry.
