[ILUG] Cups-o-madness

[Ronan Cunniffe]

Hi all,
   I'm doing my nut over CUPS at the moment.  Specifically printing in
landscape mode... as I understand it, if CUPS sees

%%Orientation: Landscape

in the postscript, it duly rotates everything by 90%.  Except that the
postscript generating programs often do this as well...

This seems to be a known bug:

  http://sdb.suse.de/sdb/en/html/jsmeix_print-cups-landscape-81.html

and the suggested solution is to sed the comment from Landscape to
Portrait, but I'm not entirely sure how to do this automatically
(manually is out, because this has to be point-and-click-land for
users)

Does anybody have a pointer to how to insert a script into the CUPS
pipeline?  Their docs are... not helpful on this issue.
