If the grocery store doesn't check these papers on the blockchain at time of purchase then counterfeiting will happen.
If it doesn't import right away and send to a new address then double spending will happen.
So I don't really see what advantage there is over using a phone to pay.

If one did this, I can imagine a lot of stores accepting BitCoin. Currently, there seems to be a looming perception that receiving BitCoin in stores requires some fancy mobile app. Personally, I find it easier to deal with $20 bills than to constantly hawk over my BitCoin accounts. If stores accepting BitCoin suddenly receive a rush of paper form BTC, then that will represent a lot of "tangible" evidence of the BitCoin economy which make BitCoin mainstream.
What about a simple program that you have installed on your computer that divides BTC automatically and prints these divisions prior to connecting to the internet (e.g. during boot?)?

Essentially you would be taking Bitcoin back into the debt system which is always bad, next thing you know people can own billions of bitcoins etc.

This idea has potential. It's already possible to get the same end result for free (bitaddress.org), but some variations on the theme could make for a novel and viable product.

The stores would need to scan the private key, initiate a transaction, etc. - much easier IMHO to just click a button on a phone.
Store display generates QR including amount. Scan with phone and pay. Much easier and more secure.
It's just a matter of time before it starts to become common.
