It means that KDEPrint can't find the enscript executable in the search
path for executable files for the current user. enscript is not shipped
with KDE or KDEPrint. It is expected to be present on the system (and, in
fact is on most, because it is a "classic" tool to convert ASCII text to
PostScript...)

If you select a filter (in "kprinter --> Properties... --> Filter tab -->
funnel icon --> select filter -->...") you'll have this info on the bottom
half of the tab:

    Name: enscript
    Requirements: exec:/enscript
    Input: text/html, text/plain, text/sgml, text/x-c++hdr, text/x-c++src,
           text/x-chdr, text/x-csrc, text/x-java, text/x-makefile, text/x-pascal,
           text/x-perl, text/x-python, text/x-tcl, text/x-tex, text/xml,
           text/x-fortran
    Output: application/postscript

The "Requirements" line means: kprinter needs to find the executable "enscript"
in order to use this filter...

(The other lines mean: "I can use the listed MIME types as input and produce
PostScript as output for you".)

Test for the presence of "enscript" on the command line of a konsole window
by issueing "which enscript"...

Same applies here.

Which filters do *not* give an error?
