ok I'll try snagit now. Turns out that zScreen only does Entire Screen, Active Window and Selected window along with some crop options but still not a full page from header to footer. PMed K3V and he confirmed and suggested WebShot so I'll give that a look too.

This is harder than I though finding this.

EDIT: WebShot doesn't work with login areas so is no good either as with another firefox plugin I tried.

Snagit works though and is what I'd now suggest having tried 6 different apps and plugins.

This can now be closed. Thanks everyone.
