suppress pop up windwo

[diego]

I'm automating the generation of PDF out of Excel sheets through
win32com.

I nearly accomplished everything I wanted, but one problem is still
left:
when I calling the print job through following code:

xl.Selection.PrintOut(Copies=1,Collate=True)

then a window pops up, where I have to input the name of the pdf I
want to generate.
Is there way to pass this filename to this window?



(I'm using 'Jaws PDF Creator" as printer.)

Thanks in advance for your help!
