Printing PDF-files with gswin32c

Dear Ghostscriptgurus,

I have no bug but a question. Unfortunately I could not find another
newsgroup for Ghostscript.
I want to print PDF-files with Ghostscript from the commandline.

I use gswin32c like this:
d:\gs\gs7.05\bin\gswin32c -dNOPAUSE -dBATCH -landscape -sDEVICE=ljet3
-sOutputFile="\\JANA\LJ1" test.pdf

Unfortunately this does not work when the Paperorientation is landscape.
(It works if I use Acrobat Reader).

1) Where can I find all the Options of gswin32c ?
2) Is there any Option for Papersize, Paperorientation for gswin32c ?
3) Is there any Option to select the Paperfeeder for gswin32c ?


thank you for your help !
