Actually, for us, the dot matrix aren't as reliable as the thermals - we are fixing more tm-u200bs than tm-88s, even though we have a ratio of about 4 to 1 on them. We are open 24 hours a day and print thousands of tickets a day and food is constantly "flying" so they get food in them, paper out sensors wear out, all kinds of problems. I understand we will always have problems with our environment, but I thought we could save some time. One store kept using their tm88s as a backup to their kitchen printer and then just kept it in place since they liked the speed. But, we run into, as you know, the problem with the paper - ruins easily in a kitchen environment if not careful plus the cost is twice as much.
