If I use the scan program in Win7 it only allows me to save documents as a TIF or JPEG. Why cant I save as a PDF ?My printer is a HP 2570. Before I changed to Win7 I had a dedicated HP Information Centre that I used to scan,save and organise in any format I or my customers chose. This program also updated automatically but is not available within Win7. Do I need to download this program again from HP or will there be a conflict with Win7 ?
