One should be careful, however.
I have done similarly by very lightly misting the backs of dried curled prints before giving them a quick shot in a heated press. The idea was to simulate the "steaming" effect of ironing shirts in order to remove the curling.
It worked beautifully. But it also had a tendency to affect the surface texture of the print. It flattened the normal textured surface of air-dried unferrotyped glossy prints. This tended to reduce the "sparkle" and give a veiled look I found quite unpleasant.
While the method described in the link doesn't use heat or clamping, it does use pressure against the surface texture of a lightly dampened print. So when using this method it might be wise to keep an eye out for those texture changes.
I should also note that I regularly fix prints in homebrew Kodak F-24 fixer, which is non-hardening. This helps with subsequent toning, but may also increase the chances for surface texture alteration.
