Old question, but if someone needs their old HP 2200c scanner to work, just use the XP 32bit driver as was suggested . . . but that will only work on Windows 7 32bit.
In my case, all my PC's are now 64bit. So I use a virtual machine with a 32 bit version of windows. Works fine for me that way. I know it's an old scanner, but I rarely have to use one, and it still functions perfectly. I see no reason to toss good hardware when there is an easy workaround the software issues. Besides, I use my virtual machine to play some really old games, so it was just a matter of installing the driver.
