scanner and OS

i reformatted my pc with 2007 OS, i tried to re-install my scanner but said the OS isnt compatible, any software that can fix this? ( as much as possible, i dont want to reformat my PC again or buy a new scanner)

Go to your model website. Download your models and makes driver and program. Or use photoshops twain protocol.

does photoshop twain protocol works on hp models?

edit:
can u post a DL link for protocol

edit again: i used the CD installer free from the model, but didnt find any option for my OS

Photoshop twain should be preinstalled when you installed photoshop.
What os are you using.
also hp model number.

HP disket F2280 is my scanner's model, i dont have photoshop in my pc

There third party scanner programs that you can buy, most are for the higher end photographic scanners and film scanners.

should i download the driver and update or driver only?
