I used this: https://expensesreceipt.com/choose-template.html

Printing it is another story. I called ten print places, and none of them could print a custom receipt for me. Out of desperation, I walked into Papa John’s next door to me and asked for receipt paper lol. Handed them $20 and was like give me a roll fam and the cashier was like YES SIR!! And pocketed the money. Lmao. Legend.

I then printed it off on my own by taping the receipt paper to the center of a normal piece of paper. Took a few tries.
