I just saved "your" PSD files as PDF files so you could print them. The PNG files are also the right size. but harder to print at home.
Every decent printshop can print PSD files at the right size.
The file is made in 300dpi, so the quality is good.
Nice design btw, great designer!
ps Can you let me know if you no longer need the files in my dropbox. They eat a lot of my space. And as this is your design I don't think others need this.
