Straightforward question here:
Is a hindering terrain marker printed hindering terrain?

Asking with regards to Shanna's power:
Common sense tells me the answer is no, but I thought there might be an outside chance I am wrong.

Thanks ahead of time!

No, printed terrain is what is on the map itself.

Even though a marker is technically printed, these kinds of effects that refer to "printed terrain" do in fact mean what is printed on the map itself.
