PDFCreator 1.7.3 Issue with default paper size (Letter) when printing with Windows7 Fax&Scan

im using PDFCreater 1.7.3 and experience difficulties with pdfcreators printer default pages size. The default pages size for PDFcreator printer is set to A4.

When I print to the pdfcreator printer using Windows 7 Fax and Scan application the
Page size is always Letter where I expecting A4.

This behaviour does not exist with the previous version of PDFCreator.

Appreciate any help on how to trouble shoot.

A complete deinstallation and reinstallation of PDFCreator did not solve my issue
