Printing from a virtualmachine


I’m tryng to print from a virtualmachine. 
PDF creator has been shared in host (w7) and additional driver for xp have been added. 
Pdf printer has been installed in the virtualmachine.
But when I print to PDFCreator printer only a blank file is generated (the name is “.pdf”, note just the extension) in the host as autosave option settings.

Is there any suggestion?
regards, Rita
