Hmm, I hope this is just a blurring/resolution issue from taking a screenshot and then shrinking the size and applying JPG. I'm using the same code and QR generator as bitaddress.org -- the only fundamental difference is the web interface, CSS/HTML and the background art.

Here's a non-downscaled sample. Would you see if the sample below reads correctly 10/10 for you? The QR codes when printed are quite sharp. Significantly sharper than this JPG.
