I used to use vueprint as my go-to image viewer on windows.
VueScan is pretty good. No drivers, OCR works well. The UI is clunky and kind of buggy sometimes, but scanning works really well (I did have problems with a specific scanner which became unstable. Could be the MFP itself though)
I purchased both VuePrint and VueScan shortly after they came out in 1998. At the time I found both to be invaluable tools, especially VueScan. I used flatbed scanners both at work and home at the time and the VueScan GUI was far superior to any other scanning software available at the time.
