I would like to hook up an lcd to my printer port (eventually i'd like to get an ic that will allow me to use serial, but right now i'm stuck with printer)

is there anything i need to know about the printer port as far as power consumption is concerned? what type of resistors should i use?

might it be possible to power the lcd off of the printer port? (i.e. pin 18 (+5v) on the Centronix end)
