Select the background color, type in some text below, then press the "OK" button. The speed of this depends on your system. You can even try pasting the whole source HTML of one of your pages. It is programmed to print tags exactly, but I've had varying results from it. If you are pasting HTML source code (including head, title, body tags) please check the "HTML Source" check box. If you are not pasting COMPLETE HTML source code, it is fine to use tags normally found within the body i.e. H1, CENTER, FORM, etc.

Internet Explorer and AOL users may get a blank page or the script may run and produce the effect. If this happens, choose SAVE AS from the FILE menu and save the blank or compiled page.
