Assumption: Size of license is 85 x 55 mm
Scanning at 300 dpi, this will give an image size of 1004 x 650 pixels
To print this image at 11.885 x 9.39 inches
1004/11.885 = 84 dpi
650/9.39 = 69 dpi
Very low resolution = blurry image
Scaling to higher image size before printing may or may not improve the printed image.
11.885 inches x 300dpi = 3565 pixels. Scale to this size.
Scanning at a higher resolution may or may not improve the final printed image
(If the actual license was printed at 300dpi scanning at a higher resolution won't help)
85 x 55 mm and scanning at 600 dpi
gives an image size of 2008 x 1300 pixels.
Less scaling is required.
