SOMETHING TO KEEP IN MIND IF YOU PRINT PAPER WALLETS ON A MFP PRINTER !!!

Found this today: https://www.youtube.com/watch?v=TCKr5WgVVN8

Closer investigation shows that my mfp printer has a HD : http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay?javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken&javax.portlet.prp_ba847bafb2a2d782fcbb0710b053ce01=wsrp-navigationalState%3DdocId%253Demr_na-c02738751-1%257CdocLocale%253D%257CcalledBy%253D&javax.portlet.tpst=ba847bafb2a2d782fcbb0710b053ce01&ac.admitted=1409502745239.876444892.199480143

Even closer investigation allowed me to retrieve EVERY document ever printed, copied or faxed on this machine...

Valid point, and one that Mycelium should warn about.

Exactly. Nowadays a lot of printers are being hooked up over the air using WiFi or Ethernet connections. If you're printing a paper wallet over one of those connections, you have to keep in mind that the wallet is only as safe as the connection you've used!

Is there any easy and trusty userguide for how to encrypt the paperwallet with BIP38? Makes me nervous.

you can use my guide with all the steps: http://www.btcguys.us/blog/how-to-create-bitcoin-paper-wallet-tutorial

I recommend transferring and then retrieving small amount before conducting large transactions

I have always been skeptical about paper wallets, only because I have a terrible tendency to misplace or damage things that are on paper...

I know that they are great solutions for most people though.   The trezor is a happy medium that I have been using lately.   I still have to keep track of the recovery seed, I like the ability to add coins and send out coins much more quickly...

Bitcoin Armory is a deterministic wallets so one key determines all the addresses a wallet will use, including all the "change" addresses. 

You can copy the key without identifying it as being associated with Bitcoin.  You can also print it using a "secure printing" feature.  I haven't looked at it too closely but it says it protects transmission from interception over the network.  In any case it is best to just use a computer never connected to any network.

A Coinbase paper wallet is a generic paper wallet. You can fund it from anywhere. You don't have to fund it from your Coinbase account.

1. Generate the paper wallet on Coinbase.
2. Print it.
3. Send bitcoins from your Bitcoin Core (Qt) wallet to your paper wallet.

I wouldn't personally use a paper wallet that is created by a website like this. If you trust coinbase enough to not somehow compromise the creating of a paper wallet then you might as well use their vault (cold storage) services. With their vault service you have a more or less zero chance of loosing your BTC because you mess something up.

No way I'd ever use a "vault" storage. Vault storage is just a fancy way of a total stranger telling you: "hey! let me take care of your bitcoins for you!"
I remove any penny from CoinBase as soon as I do a transaction. I wnt full control over my BTC.

Well if you are trusting coinbase to securely create your private key, then I don't see why you wouldn't trust them with your actual bitcoin.

If you want to have 100% control over your bitcoin then you should use something that creates the private key on the client/browser side.

Yeah,absolutely bitcoin qt should itself possess a paper wallet printing feature,It would be best rather than using other services

Yet another feature that should have been put into the QT (core) client months ago, but the dev team hasn't bothered.   Awesome progress.

I also love that I have to write CMD commands into a command prompt in longhand after 3 menu navigation clicks that make zero sense, just to import a wallet.   That's also awesome.   Exactly how much time would it have taken them to make that about 500x easier?   Yet there it sits, and I have to google the "step by step process" every time I need to do an import.  Awesome progress, dev team.
