[cups] stopped "Filter failed"

[Jerry]

CUPS 1.7.3 on FreeBSD-10 amd/64

I cannot seem to get CUPS running correctly. When trying to print, even using
the CUPS web page and trying to print a text page, I get this error message:
"stopped "Filter failed"". I copied this out of the error log:

I am not sure what the problem is or what to look for. I am hoping someone
can assist me. I can obviously supply the entire log if requested.
