The *only* script change [[ at least that I can see ]] is that "sOutputFile=" now fails to understand /dev/fd/3. I got my old "hpif working with only-ASCII and your version working with only-[Gh|P]ostscript, or mostly since your file did print some ASCII. But for me, it hung for some timeout or <???>. I dropped in your Postscript working lines, minus the re-direction stuff and voila! Yes for good old fashioned ASCII and Postscript both. Appended if my new hpif. (I have four servers with /usr/local/libexec/hpif, so name-change rather than change four /etc/printcaps:-). thankee, thankee! gary PS: file appended. note lines 39-46... .
