Umm, how about reading what the assignment requires? We can't help you with homework if you don't even tell is what it actually is. 'financing report' is more than a little vague. We're not your teacher so we can't guess what his requirements are.
lets see, are you trying to ask what amount of power a printer will deliver over an amount of time. if that is the case you need to read the technical spec sheet for the particular printer. hopefully it will furnish you with information such as its power consumption and specifications of that sort. and like sceadwian said. we cant see this and know what is is exactly. if you post up the exact question, then maybe we might be able to help.
