Office 2007; Chart doesn't appear when no network

Problem: Only in Office 2007 a chart doesn't display, also printers are unavailable when no network present

In office 2003 everything works fine,
but in Office 2007 chart doesn't appear when network cable is disconnected. It turns out as grayed out, blank with background colour, with no selections available (as shown in picture). Also when there is no network, all printers or even print preview is unavailable - including pdf makers, local printers, network printers... Word works ok, this problem appear only in Excel.
Chart is displayed with no problem when network is connected and all printers are available when network cable is connected.

Problem was the default printer:
Microsoft XPS Document Writer

Once some other one was selected as the default one, everything worked fine.
