Thanks for the info. I'm assuming this one has the first kind, but I'll take it. Apparently you are much more precise than I am about printing. LOL. I look at the spool but don't necessarily do the math to make sure. When the roll starts getting low, most of the time I keep checking when it's questionable, but things happen and I forget. And sometimes I misjudge when I leave a print running. Hasn't happened often - I guess if it did I would start doing the math.
