I don't know anything about ENVI, and I don't know a lot about the JPEG
spec, but in my experience JPEG images don't store dpi info in their
header (or at least I haven't used a program that reads it).

So if you want a final image with a greater dpi just export a larger
image. For a 2" x 2" 300dpi print image, export a 600 pixel x 600 pixel
image from ENVI.
