I got an LCD from an old table phone and wanted to play with it a bit.?

I found out that you can send msgs to the LCD for it to show by connecting it to the parralel port. I really want to know about both the parallel port and how the LCD functions. In a simple way ofcourse?

May be hard to do without some data on the LCD. Generally they are serial driven and have on board microprocessor to translate the codes sent into text and position on the screen. IF you are lucky you may be able to just send text as ASCII characters.
