The printer is a high volume postscript printer which is connected to
our network. So the data is sent over ethernet. We have two ways sending
the data, either over CUPS or over the Windows Spooler. If I open the
pdf document (with the AcrobatReader) on a Windows computer and start to
print, the printer just starts to print after a few pages sent. If I
send the pdf via lpr/CUPS the whole document has to be processed(which
takes a lot of time). And after that, the printer starts to work.   
ON windows computers the printer only prints at its fully speed of
105ppm when Acrobat Reader 5 is used and Level 1 is selected.

I will try this.

I currently work on this option, but till now with no luck.
