I am an accountant & use the paper rolls daily. In the past I have never had the paper jam in my calculator because it is so thin. This cheap paper makes it hard to tear off a tape evenly & it jams very often. I am not happy with this purchase. I have been an accountant for over 40 years & have never had this problem until I ordered this from Staples. This is the second time I have ordered these rolls of paper thinking I must have gotten a bad batch....no these new ones I just received are the same thin cheap paper. If you have a suggestion of what to buy & where I would be most appreciative.
