BRILLIANT!!!!!!! You deserve every dollar you make from your extraordinary program and service. THANK YOU SO MUCH! In awe of you, that you could produce, make, create this reset program so that even I, 78 yrs. old, mostly blind and not much of a computer geek, could do it! I al thrilled and jumpinga round because you saved me about $300>$400 from not having to buy a new printer.
