can jtwain be used to interact with a finger print scanner…
TWAIN can be used with anything that outputs pixel images provided someone (almost always the manufacturer) has developed a TWAIN Data Source (DS) for it. If you don’t know if a DS is available for the finger print scanner, contact the manufacturer to find out.
If a DS is available, the second issue is to determine if it’s compatible with jtwain. I can’t help you there.
