For print resolution, almost all professional printers are limited to 300dpi. No matter what your image size or resolution you cannot achieve greater than 300dpi print resolution. The resolution your image will print at depends on image resolution (pixel x pixel) size and size printed on paper. For an image that is 3072x2304 any size physically printed from 11"x14" and lower will be printed at 300dpi which is photo quality. Even printing this size of image up to 20"x30" which will be slightly lower dpi, will provide a fairly high resolution image.
