Left for 2 days but seems there are no prints. How do you think, what might be the reason?

Mycelia P: to make a spore print you totally remove stem place cap on foil, make sure cap is in contact with foil put one drop of water on cap and cover with a cup. Shroomok: Maybe they already drop spores before you cut the cap. Some strains have white/transparent spores, but it's not about GT. Try again with the next flush
