How do you find out if your scanner is twain compliant?

To determine if your scanner is TWAIN compliant, check the manufacturer's documentation or specifications for the device. Look for the TWAIN logo or mention of TWAIN compatibility in the product details. Additionally, you can try installing TWAIN drivers—if the scanner recognizes them and allows you to use TWAIN-compatible software, it confirms compliance. Lastly, you might also find information on the manufacturer's website or support resources.
