Welcome to TSF !
OK, let's hope there is an easy fix here, try looking in your printer's utility for a control (check box, perhaps) associated with this function.
To open your printer's utility do this: (under XP)
Start > Control Panel > Printers and Faxes > Right click on your printer's icon > from the drop-down menu, choose Properties
You now are looking at your printer's utility (and driver) user interface.
There are lots of controls and settings. Note the tabs above.
See if you can find the Test Page control from there.
If you can't find it, post back with your printer's make and model.
