For over a week, my printer has refused to print. It kept telling me I had a bad cartridge-I tried 3 and still got the same message. Took me all afternoon, and several downloads and it now works!! Since we homeschool, I was kind of at a loss. Good think it was a holiday week! Next week we will hit the math a little harder to catch up. I had their lessons all printed out at the time except for the math--thats when it broke. (I try to keep a week ahead on our planning, so if we go out of town suddenly or something, its all ready). If I had printed it at the library, they charge 20 cents a page, plus the gas and time getting there.
