<br /><br />
<span id="instructions3"><b>Step 1: Calibrate Printer</b> Before printing out a wallet you'll need to "calibrate" your printer for <b>zoom</b> and <b>horizontal shift</b>. Without proper callibration, your wallet will end up the wrong size or with a misaligned reverse side. Don't forget to write down the zoom/shift values for the next time you need them.</span>
<br /><br />
<span id="instructions4"><b>Step 2: Print Front</b> Next we'll print out the front side of your wallet. A public address and private key will automatically be generated.</span>
<br /><br />
<span id="instructions5"><b>Step 3: Print Back</b> Then you will put the same page back in your printer (but upside down) to print out the back side of your wallet. This isn't just for good looks: the back side design includes additional tamper-proof safeguards.</span>
<br /><br />
<span id="instructions6"><b>Step 4: Cut, Fold, Seal & Fund</b> Find your scissors! Time to cut out your wallet, fold it, and seal it (use <a href="https://bitcoinpaperwallet.com/index.html#purchase" target="_blank">tamper-proof holographic tape</a>!) Now you're ready to transfer bitcoins from your online holdings to your new wallet.</span>
