All modern technology exists within Yggdrasil, computers and printers included. The only reason cars and the internet don't exist in the city of Asgard is because the gods decided amongst themselves that those specific inventions were detrimental to the environment; all other technology still exists, and even those products can be found in other kingdoms ( mostly Utgard though, because Loki doesn't care about things like clean oxygen, losers ). There could still exist a place to print your photos within Asgard, but computers would probably only be found in a junk shop or black market trade because Asgard natives have no real use for them.

Long explanation just so that you are aware these things and more are absolutely possible! You just have to do some creative plotting to get there, which was part of the intention in setting those game mechanics, if that makes sense?
