I had exactly that problem on my own today!
I resolved it, when I UNINSTALLED the AcrobatDistiler from avaiable printers in printer control menu (under KDE destop, Mandrake Linux 9.2).
It seems that somehow OpenOffice (at least Write) when AdobeDistiler (acrobat) is instaled from KDEprint menu, manages that it can be "seen" only that "generic" ps printer, and PDF writer...
In the same time ALL other applications was able to "see" and print through all avaiable&installed printers..
Anyway, after deleting AdobeDistiler from the list of avaiable printers in KDEprint menu, and restarting of OpenOffice Writer, everything was OK...
