Review on 5 Pack Labelife Compatible Label Tape Replacement For Brother P Touch Label Maker- Laminated, Black On White, 1/4 Inch X 26.2 Feet (TZe-211 TZe 211) –Ideal For PT-D200 And PTD600 Models by Matthew Sutton

They are not compatible and do not work on PT-1880 as advertised. Printer will show no cassette when loaded with this tape.I’ve attached two pictures. The grey one on the top is the standard tape, this black tape is on the bottom. Notice the pin holes are not the same which causes incompatibility.After some study, I found that it is fixable (at least for PT-1880). Just put a tape to depress the second pin down as shown on my other attached picture.
