Not necessarily, it just means something is wrong with the filter.  Is 
print/enscript-letter or print/enscript-a4 installed?

The filters can be tested directly.  Send some text to the filter:

   lptest | /usr/local/libexec/enscript

It will produce a bunch of PostScript output, the last lines of which 
are:

   %%Trailer
   %%Pages: 4
   %%DocumentNeededResources: font Courier-Bold Courier
   %%EOF
   [ 4 pages * 1 copy ] left in -

If that does not work, check the contents of the 
/usr/local/libexec/enscript file and the permissions set on it.
