HP TWAIN drivers for Server 2003

I’ve got a HP C4183 All-In-One printer & scanner (part of the C4100 series) that I want to install on a Server 2003 machine. It seems that HP doesn’t support this OS for some crazy reason so the software supplied with the printer does not work on Server 2003. I’ve managed to get the print portion working but I’m having trouble getting the scanner setup.

Are there TWAIN drivers that I can use that will allow me to scan using this scanner? Or is there some other workaround I can try?
