The screen
The sale already went through. Sale #4192 — $8.95, paid debit. The customer paid and it's recorded. Only the paper copy is missing.
Don't ring it again and don't void it. The sale already happened, before the printer ever jammed.
Keep selling. A jam only stops the printer, not the till — ring the next customer exactly the same way while this gets fixed.
Clear the jam or load new paper, then reprint below. Reprinting sends this SAME sale to the printer again — never a new one, never a changed total.

Tell the customer it's coming — they don't have to wait for it.
If the customer can't wait
Hand them the sale number, #4192, written down. It's already recorded, and reprinting later doesn't need them standing here.
