Part: Brother TZe cassette, up to 12 mm · TZe family; 3.5 mm, 6 mm, 9 mm and 12 mm widths
Fit and restrictions
The PT-D210 accepts Brother TZe cassettes in 3.5, 6, 9 and 12 mm widths. Brother lists standard laminated, Flexible ID, extra-strength adhesive, iron-on fabric and non-laminated options.
12 mm is the cassette-width limit; a genuine 18 or 24 mm TZe cassette is too wide.
TZe-231 is a documented 12 mm black-on-white option; the consumables table also lists other colours and materials.
This discontinued printer still has an official consumables table; discontinued hardware does not make every old cassette interchangeable.
Restrictions
DK rolls, DYMO D1 and Epson LabelWorks cassettes use other systems.
The sources here establish the US model and its US consumables list.
Part: Brother TZe cassette, up to 24 mm · TZe family; 3.5 mm, 6 mm, 9 mm, 12 mm, 18 mm and 24 mm widths
Fit and restrictions
The PT-D610BT prints on Brother TZe tape up to 24 mm wide. Its official consumables list identifies exact colour, finish and width references, including the 24 mm TZe-251 black-on-white cassette.
Accepted widths run from 3.5 to 24 mm; 36 mm tape is outside the limit.
A printed label can have margins: tape width is not the same as maximum print height.
Use the exact consumables entry for decorative ribbon, fabric and specialist adhesive choices.
Restrictions
The automatic cutter does not make every material suitable for every use. Follow the material instructions.
