When upgrading to Access 2003, it may be necessary to download and install updated printer drivers from the manufacturer's site.

There are two notable symptoms:

1) From the database window, you click the Reports tab, then click New; select a report type and click OK -- nothing happens.
2) From VBA code that uses DoCmd.OpenReport -- report does not open, but receive error 2501 Action Cancelled.

This seems to occur when upgrading from Access 2000-2002, especially on Windows XP.
