Welcome to Windrivers peterhain. The printer is a Dell A920 which is 7 years old and has worked for my client all these years until recently. When they installed a new Belkin router, they used the CD to install with which in return installed a backup program causing the problem. FYI, You will find XP SP3 is still supported on all printers for the most part until April 2014 when it then becomes obsolete. Thank you for your input.
