How to print a test page from a Dell 1130 / 1130n laser printer

You can print a demo page or test page from a Dell 1130 or 1130n printer, which can help troubleshoot potential problems.  To print the test page/demo page, hold down the Cancel button (the button with the red triangle inside a circle) for about 3 seconds or so.  The green LED will start blinking, and the demo page will print out.

On the Dell 1130, this demo page may also include some configuration and status information about the printer.  For the Dell 1130n, you can find this configuration/status info on the configuration page.
