In that case: you can still add a QR-code. My favourite is a paper wallet (don't use the site that turned into a scam) that prints the private key twice, one of them upside down. That reduces the risk of losing it if the paper gets partially damaged. You can of course easily do this manually.
Creating 1000 individual QR-codes would be very easy to script on Linux, but a tad more work if you also want to keep track which address belongs to each QR.
