after conversion with 'pstops' option '-o media=Tray2' is ignored

[ekkard gerlach]

After a conversion of a simple ps-file hl5250kasse_raw.ps  with 'pstops' 
to hl5250kasse_raw.ps  the option e.g. '-o media=Tray2' is ignored. The 
second ps-file can't be printed to a certain tray using CUPS. I tried 
tray1, tray2, MPTray, Tray3 is default. Printer is HL 5250. WHY?

Look at the files:
http://aiai.de/hl5250kasse_raw.ps
conversion: pstops "0 at 1(3cm,0cm)" hl5250kasse_raw.ps hl5250kasse.ps
Result: http://aiai.de/hl5250kasse.ps

The conversion moves the content 3cm to right.

lp -d pc16_ps -o media=Tray2  hl5250kasse_raw.ps  is printed to Tray2
but not:
lp -d pc16_ps -o media=Tray2  hl5250kasse.ps
hl5250kasse.ps is printed to default tray (MPTray)


diff hl5250kasse_raw.ps hl5250kasse.ps

How can I print  the result hl5250kasse.ps 
     to a certain tray?
