I have always felt that printing is an important and significant step in the photographic process. Printing completes the cycle so to speak. Rather than just viewing images in your computer screen, printing lets us physically hold and enjoy the images.
Once I print my images, I like to wait about 24 - 48 hours to spray the prints. I use Hahnemuhle Fine Art Protective Spray to help protect the prints against scratches and enhance U.V. resistance. The prints typically sit overnight prior to me handling them and getting them ready for matting and shipping.
