Sometime Today, Rishi Gangoly assembled some asciibets to say:
This is what HP has to say about scanning software for one of their Scanners we happened to buy a few years back. :-(
so did you bother checking the links that they sent you? or were you waiting for someone on this list to do that work for you? If you had checked the links, you would have found out that your scanner is supported by xsane.
I'll leave it to you to figure out which backend to use.
