I purchased the PDF two months ago. I had no issues with printing it, as far as I can tell there is no DRM on the file.
BTW: I happened to be just about to build a new firewall for my house and found this book to be a great resource. I purchased the Soekris kit (because of the 3 NICs and I wanted 100G of files) and the book really helped.
