printing PDF-files with gswin32c

[Leopold Zyka]

Dear Ghostscript gurus,

I dont have a bug but a question but I could not find another newsgroup
for ghostscript...
I want to print PDF-files with ghostscript. I use gswin32c which works
but I have the following problems:
1) how can I print in landscape ? (I could not find any option so i
tried -landscape)
2) how can I select Papersize ?
3) how can I select a Paperbin ?

My commandline looks like this:
d:\gs\gs7.05\bin\gswin32c -dNOPAUSE -dBATCH -landscape -sDEVICE=ljet3
-sOutputFile="\\JANA\LJ1"  test.pdf
Although the pdffile is landscape it gets printed in portrait...

thanx for your help !!
Leopold
