I'm still interested in a couple.

The only issue with the concept device is the fact that some printer has a buffer which contains the printed data and it won't be deleted.

They don't talk about it but they are saying "use it on a printer that you can trust".

Printer buffers are usually stored on the computer sending print jobs. If a printer has a buffer of its own, it would most likely be stored in volitile memory and cleared once you power off the printer. For maximum safety, you could always throw the printer in a fire after printing your wallet Wink

I'm more concerned about the technology producing the entropy. I'm not really familiar with static RAM cell power states as a source of randomness, but hope that the technology was implemented correctly and is generating truly random numbers.

some printers have hard drives, so you'd want to carefully examine your printer's features to make sure you don't end up with a copy of your wallet on a printer's hard drive.
this post is a good starting point:

Besides using static RAM, we have also added the built-in RNG chip, and gate noise as sources of entropy. You can also add your own Diceware salt to it just to be doubly-sure, and it will print out a hash along with the paper wallet to prove that the salt was used correctly.

I decided to (with lead in my shoes) to pay up to Zeushash to make sure my GHs I contracts weren't cancelled there so at this point I won't be buying one, sorry.
