We turned that off.

My investigation indicates that both are sent.  The global prepended to the
device setup.

Both are off here.  We originally had this set up to work with LJII's and never
bothered with it as the printer models changed.

Ah, if only I knew then what I know now.

In this case both the ENV file and the spooler were prepending PCL commands. 
The spooler was setting the reset commands.  I determined this by removing the
ENV clause and examining the result.

So, what I did was handle this on the virtual end.  The remote command that I
am using at the moment, and which successfully merges the print file with the
invoice overlay, is this:

socat TCP4-LISTEN:9101,bind=192.168.216.179,fork,reuseaddr,su=hp3000 \
      SYSTEM:'sed -r '1s/^.{42}//' | \
      cat /var/spool/hp3000/forms/hll_inv_ljiii_85.ovl - | \
      gpcl6 -dNOSAFE -dNOPAUSE -sDEVICE=pdfwrite \
      -sOutputFile=/var/spool/hp3000/np4178/HP3000-INV-\"$(date
-Iseconds)\"-%03u.pdf -' &

The sed utility strips off the first 42 characters, which comprise all of the
PCL added to the HP SPOOL file, and pipes the STDOUT result to cat.  The cat
utility prepends the PCL auto macro overlay file to the STDIN stream ( - ) from
sed and pipes that to gpcl6 which then reads cat's STDOUT from its STDIN ( - ).

The rest of it just sets the output to pdf, timestamps the result, and
identifies the data source (hp3000/np4178).

At this point I can create regular reports as pdfs and merged invoice form pdfs
directly from the HP3000 and place them on our WebDAV resource. Which is a long
way from where I started with this.  I just was looking for a PC utility to
read spool files.  Talk about falling down the rabbit hole.

If you ever run across the details of how this is done entirely on the HP3000
using an ENV file then I would appreciate having that information.  Is it just
as simple as pointing the ENV to the overlay file?

Regards,

P.S. respecting FCOPY.

Is there a parm to turn of the file size mismatch warning?  In jobs I use
HPMSGFENCE, but that nukes everything.  I just want FCOPY to shut up.  I
suppose I could write a UDC, but, . .  meh.

I cannot find such an option in the FCOPY manual. But, that usually means I am
either looking in the wrong place or that I do not understand what I have
found.

Thanks.
