The answer is that you will transport that paper electronically. You keep a compatible file copy either on disk or via e-mail. Keep that disk in your notebook and update it whenever you work on it. Do not format your work or add graphics until the very last draft at the computer with the printer. The e-mailed file should be in a text format if you use different word processors.
E-mail the copy to an address that can be accessed at school or the destination computer.
E-mail the copy back home when you complete it at school. Avoid adding graphics or formatting to the e-mailed copy. Do not format your work or add graphics until the very last draft at the computer with the printer. The disk will be easiest at least at first. You can keep a PC formatted disk with your file on it.
