By searching for old emails on this subject, I'd say try this,
if you don't have the stc.upp file already like this:
2001-nov-20::::::::::::::::::::::::::::::
We need to say that the string of hex numbers goes at the
very beginning of the dupBeginPageCommand string value
(according to my stcany.upp file).
Would a patch file help?
-dupBeginPageCommand="<
{insert new hex values here}
{leave previous hex values here}
>"
2001-mar-01::::::::::::::::::::::::::::::
00 00 00 1b01 40 45 4a 4c 20 31 32 38 34 2e 34 0a 40 45 4a 4c 20 20 20
20 20 0a
~~~~~~~~~~~~~~~~~~
This hex string goes in the file (on my system)
/usr/share/ghostscript/5.10/stcany.upp,
inside the "dupBeginPageCommand" string. If there are
already some hex codes there, put these _first_.
HTH.
