Print Preview - how to disconnect from Printer

[JohnGB]

I have a form which by necessity contains your Print Preview and a another 3rd Party printer for PDFs.
The problem I have is that the PrintPreview seems to grap the printer and the output from the PDF printer never reachs the spooler.
If the PrintPreview is removed from the form the PDF printer works.
Is it possible to detatch the PrintPreview from the printer while printing from the PDF Printer?
