After a hiatus for the last 2 months
http://printcoins.com is back up and selling bills. Right now I am just selling bitcoin cheques, but will be back to selling denominated bills again too soon.
Also, I am working on making the pdf generation system available so others can print bills themselves, and perhaps in their own language. When I do this, I will make it so other bill printers can advertise on printcoins.com, so it will be more of a hub of mints rather than focusing on being a mint itself.
