Some printers default to printing pages in reverse order (or printing the
last page first).
You can usually resolve this issue by changing your printer Properties settings.
To do this task in Windows XP:
Click the Windows Start button.
Click Settings and then click Printers and Faxes.
Select your printer.
Go to the File menu and click Properties.
Find the option that determines whether the first or last page prints first.
Make and save your change.
To do this task in Windows Vista:
Click the Windows Start button and click Control Panel.
Under Hardware and Sound, click Printer.
For more information, refer to the documentation that came with your printer.
