Problem with normal printer after PDFCreator was installed


I'm using narrow printer called Posiflex PP 7000 (LPT1). After installation PDFCreator as PDF printer I noticed many problems with my PP printer. I tried to remove PDFCreator by Add/Remove programs but my problems didn't gone. Could someone tell me which files (system files) should I restore from Windows Installation CD? Or how can I uninstall PDF Creator definitively?
