I believe that sometimes there are regulatory requirements to print receipts (as a transaction without a receipt is more likely to be cash-in-pocket tax avoidance).

My parents lived in Greece during the financial crisis, and at the time the tax agency would randomly audit people and require them to present 25% of their yearly income in the form of receipts. This was introduced as a way to get consumers to ask vendors for receipts (as a way to force them to input sales into their cash registers and book them as income)

Though it is quite ironic that most original receipts don't last long enough for any audit purposes. In Australia businesses need to keep all receipts for 7 years (and for individuals it's 5 years), for tax audit purposes. But I have yet to encounter a paper receipt which lasts more than 2 years.

Yeah thermal paper is pretty terrible. Also make sure you don't forget one on the dashboard of your car on a hot sunny day... At least where I live scans of receipts are accepted so I just scan everything

Since we live in the future, they could just e-mail the receipt directly to the guy who checks their tax returns.
