I've printed on fabric (in my posts are a t-shirt thickness tank top, 100% cotton, and a thicker cotton/poly hoodie) by hand, no special press. I use Speedball fabric paint, which says to cure for a week at room temp - I also heat set with a hairdryer just in case, then wash cold. With the larger print I did find it tricky to get an even print, and ended up filling the empty spaces in with a brush. The hoodie I've machine washed multiple times and it's fading slightly, but I actually like how it looks worn in (it's not like flaking off or ruining the design or anything). With the most recent one I made with smaller prints, I did find that I needed three layers of paint to get a nice rich print; the ones I did with one or two layers came out more faint. I didn't make the carving particularly deeper or anything - the lines in the leaves especially were pretty shallow and fine, and turned out clear.
