Peripheral

What make and model of printer are you using? What operating system are you running?
How is your printer connected (USB, parallel, networked?).

When you say it will only print a test page do you mean the test page that you initiate from..
A) the printer settings dialog in your operating system, or
B) from pressing buttons on the printer itself?

If A) then it may be that your default printer has been changed to another print device (maybe a PDF Writer or Microsoft Document Writer).

If B) then I suspect there is a connection problem, possibly loose cables, or, if this a network printer then there may be a network problem.

Sorry if I a bit vague, but if you can provide some more information then I or someone else may be able to help you more.

Good Luck,
Rob
