Welcome! Let's print out a beautiful and secure wallet for your Slack!Here's an overview of what will happen, step by step.
Step 1: Calibrate Printer
Before printing out a wallet you'll need to "calibrate" your output using the zoom and horizontal shift adjustments to accommodate your particular browser / printer combination. Without adjustment, your wallet may print out too small or with a misaligned reverse side.
Step 2: Print Front
Next you will print out the front side of your wallet. A public address and private key will automatically be generated, or you can supply your own key by rolling dice, shuffling cards, etc. You may also duplicate an existing paper wallet or provide a "vanity" address if you have one. If you are printing several wallets, it's possible to print two per page.
Step 3: Print Back
You will put the same page back in your printer (but flipped over) to print out the back side of your wallet. This isn't just for good looks: the back side design includes additional tamper-resistant safeguards.
Step 4: Cut, Fold, Seal & Fund
Find your scissors! The final step is to cut out your wallet, fold it, and seal it with tamper-evident hologram stickers or at least opaque (light-blocking) tape. Now you're ready to transfer funds from your online holdings to your new wallet.

The calibration step helps line up the front and back sides of your printout. Print out this page in LANDSCAPE (wide) format. Based on the results, adjust the "zoom" and "horizontal shift" until your printed ruler (1) approximates a real ruler, and (2) is horizontally centered, leaving approximately equal margins on the left and right sides of the page.

In this case, simply enter your private key in Wallet Import Format (or scan it using the "validate" feature on this web page.) WIF keys always begin with the number 5 and look something like this: '5JnwJNC7q3...' The public address, e.g. '1vanityABC456...' is automatically calculated using the private key, so you only need to provide the private key.
If you want to roll dice or shuffle a deck of cards to generate a key:
Maybe you don't trust that this software (or computers in general) can generate sufficiently random numbers. In this case, you can supply your own random data points from virtually any source. For example, you can roll a six sided die at least 62 times and enter each roll in sequence, e.g. '15249385...' Or, you can mix up a deck of 52 playing cards (after thoroughly shuffling it at least 10 times) and enter at least the top 31 cards in this format: 5S-10H-AC-... (where 5S = 5 of Spades, 10H = 10 of Hearts, AC = Ace of Clubs, etc.)
No special formatting is required. Just type in a great deal of (truly) random text from any source, and whatever you supply will be SHA256 hashed and converted into a private key and public address.
If you want to make a paper wallet which can also be accessed using a passphrase (AKA a "brain wallet"):
You can make a so-called "brain wallet" by supplying a VERY secure passphrase like '1852 Adobe Cloud SMASH fuzzy steamzonk bob slack econocalypse'. Be extremely careful doing this because a wallet generated using an insecure passphrase is virtually guaranteed to have its balance stolen within minutes of receiving funds!.
The resulting paper wallet will still have an ordinary crypto-looking private key and public address, but you will also be able to retrieve your wallet contents by entering your passphrase into the 'verify' tab of this service or a similar service such as brainwallet.org.
Note: supplying a brain wallet passphrase is different from BIP38-encrypting your wallet with a passphrase.
About "BIP38" Encryption
The advantage to encrypting your paper wallet is that if your paper wallet is stolen or otherwise exposed, the balance on the wallet is safe unless the passphrase used to encrypt the wallet is guessed. However, if you encrypt your private key with BIP38 and you lose your passphrase, it will be impossible for you to recover the funds you have sent to this wallet.
Also, note that not many wallet applications or web services are able to import BIP38 private keys. In this case, you will have to use the "Validate" feature on this webpage to extract the unencrypted Wallet Import Format (WIF) key as an intermediate step before sweeping the balance.
WARNING: Before sending any funds to a BIP38-encrypted wallet, first do a test make sure you are able to decrypt the printed private key back to ordinary WIF format.
In short, if you do not have a strong understanding of the BIP38 encryption and decryption workflow, click cancel, print your paper wallet out without encryption, and keep it safe the same way you would jewels or cash.
Reload the front page into your printer first. Note: The back design is intentionally larger than the front side. (Use the front side as your guide when cutting to trim off the excess.)Print Wallet Back
How to cut & fold your 2-sided wallet:
Now fold the more narrow private key area in half, and then over again as indicated by the dotted lines in this diagram. The unusual "butterfly" shape can be a bit of a pain to cut out, but it's essential to keep your private key safe.
The final wallet will be a rectangle shape with the more narrow private key area folded over it.
Seal your wallet by placing two strips of sturdy light-blocking tape over the top and bottom edges of the private (folded) area. A zip-seal bag will keep it safe from moisture (especially important for inkjet prints.)
Purchase hologram stickers and/or zip-sealing bags »
How to add funds to your wallet:Send Dobbscoins to the address (or QR code) where your wallet says "PUBLIC ADDRESS".
How to withdraw funds from your wallet:You should expect to withdraw the entire balance of the wallet by importing it (or "sweeping" it) to a live wallet, e.g. a Dobbscoin wallet application.

Public and private details for:
Use the Public Address to receive funds or check your balance online. The Private Key WIF is a code that needs to be keep secret since it can be used to spend any funds that have been sent to the corresponding public key. Keys can be encoded in a number of different formats. The most popular encoding formats (WIF, WIFC, HEX, B64) are shown below.
