Did you ever think that your printer has a mind of its own? The first problem we had was when we first bought our computer the old computer didn't work with it. So we went out and bought a new printer which the new printer likes to work one minute on command then the next it doesn't. After having the new printer for about two months we found a download online that will let our old printer work with the new computer. Needless to say I took that new printer and booted it to the curve.
