script to install network image scanner

Afternoon,

Does anyone have a script to install a network image scanner via it's IP? 

I have multiple locations with multiple PC's which are all being upgraded to Win7 and each location has it's own HP MFP. I've got a script to install the printer but need one to install the scanner in Scanners and cameras, otherwise I'll have to log into 800 PC's to set-up the scanner. hoping for a script to add the scanner for all users, so windows Fax & scan can be used.

Hope that makes sense and you can save my sanity.

Thanks
