The basic idea is in the title, so I want help expanding/reworking it.
The object is a printer that constantly has a single sheet of paper exiting it. This paper contains a crossword puzzle that just goes on forever. The printer only dispenses more of the puzzle once all of the paper that's accessible has been fully solved.
Answers to the puzzle can be in any language as long as they've been romanized to English. All unique answers can only be used once. Additionally, some answers are SCP-specific words such as "keter" can appear as answers, which would lightly concern the Foundation, I suppose.
Thank you for reading this, and for any advice you might be able to give me.
