I recently purchased a HP Officejet Pro 8500 (A909a) and it's ethernet attached. It's been configured and works perfectly from WinXP, Win Vista, Windows 7, and Fedora 11 x86_64. However, on my machine running CentOS 5.4 x86_64 I can't get the configuration to work so that it prints duplex (2-sided). The HP Setup appears to be working from the command line, but the graphic portion doesn't appear to work. Any ideas?
