Is there a way to simulate hitting a key to continue printing the output to a file?

Send "\n" to the terminal.

However, it might be best to switch off the pager at your bash prompt:
There may be a "pager" setting in the shell, or as this is bash, there may be a "$PAGER" environment variable to unset: export PAGER=""

Unless, of course, the show out command has the pager built in. In that case, use the manual for that command to find out how to switch of paging.
