One of our Remote Offices has a HP M1212nf printer, which they use to Scan to PDF, the issue is the at the PDF files are too large when using the ADF. The default resolution is 300dpi and this is just to high, especially when 99% of what is being scanned are black/white documents that really only need 256 grayscale, at 50% scaling size and 100 to 150dpi. When you choose to use the ADF to scan instead of the flatbed, it defaults to 300dpi and I'm unable to change it. I even tried the XP built in scanner software and it does the same thing.
Any ideas? I thought to install our Adobe Acrobat X Standard, but if I understand correctly it will just use the HP Twain Driver as well, so same issue
