How do I enlarge an image I scanned with Epson Scan 2?
You can enlarge your image in third-party image-editing software. To create a high-quality image, increase the Resolution setting of your scan by the amount that you want to increase the image size. For example, if you plan to double the size of a 300 dpi image, select 600 dpi as the Resolution setting in Epson Scan 2. Open the image in image-editing software, double the size of the image, and set the print resolution to 300 dpi.
