printing parts

help! i can't remember how to print individual band parts from a score! can't see anywhere in the handbook and know it's really simple because i did it last year. i think i need to create a new 'tab' along the top of the score so i can not only see the full score, but the individual parts there too - and toggle between them. from there i think i can print - and alter the size for optimal reading.
thanks to anyone who can help.
