Review on 6-Pack 18Mm 0.7" Compatible Brother Ptouch TZe-241 Laminated White Label Tape Replacement For PTD400AD, PT-D600, And PT-P710BT Label Makers by Gus Pierson

These cartridges are not compatible with the Brother P Touch label machine!I installed one, and it would print backwards (mirror image). It turns out there are two little knobs that this cartridge is supposed to push down to tell the label maker to print properly, not mirror image. The two little pegs on this cartridge do no line up properly with these knobs, so the labeller thinks it is supposed to print mirror image.You can fix this by taping those two little knobs down on the labeller, but that is a temporary fix. The tape will eventually work it's way off, the knobs will pop up, and the labeller will print mirror image the next time you use the label maker.Not compatible
