Check the exact P-touch model before choosing a cassette
The P-touch name covers several Brother printers. Read the full model code on the machine, then check the label inside the cassette cover or Brother’s exact model specifications. A cover marked M is a clue for the M tape family. The TZe prefix identifies the cassettes used by models such as the PT-H110. Brother PT-M95 specifications · Brother PT-H110 specifications
| Printer model | Cassette family | Example of supported black-on-white tape |
|---|---|---|
| PT-M95 | M, 9 or 12 mm | M-K231BZ, 12 mm × 8 m |
| PT-90 | M | M-K231BZ, 12 mm × 8 m |
| PT-H110 | TZe, 3.5 to 12 mm in listed widths | TZe-231, 12 mm × 8 m |
| PT-P300BT P-touch CUBE | TZe, 3.5 to 12 mm in listed widths | TZe-231, 12 mm × 8 m |
| PT-N25BT | Btag | Check the Btag supplies listed for this model |
The Btag example is another reason to read the model code. The PT-N25BT connects to the same Design&Print 2 app as the P-touch CUBE. Its compatible cassettes are Btag. Brother Btag model guide · Brother PT-P300BT cassette list
For an M tape printer, match the M code and length
For the PT-M95 or PT-90, Brother lists M-K231BZ as a 12 mm black-on-white plastic tape. The 8 m cassette is a practical option for files, smooth storage boxes and other ordinary indoor labelling. If you are replacing tape from a starter pack, check whether the old cassette or listing instead says M-K231SBZ. Brother lists that as a 4 m version. Both have the same colour and width.

If the job calls for a more durable label than your usual M tape, check the specific material and what Brother lists for your printer. The protective laminate on TZe-231 is part of that particular TZe cassette. Your printer’s cassette family determines which supplies are available for the job.
For a TZe printer, check width and finish within the family
If your printer is a PT-H110 or PT-P300BT, TZe-231 is a listed 12 mm black-on-white laminated cassette. Use it when the surface has enough flat room for the full width and you want black text against a white background. The laminate covers the printed layer. For a narrower folder tab, check the supported 9 mm TZe-221. Other TZe codes identify different materials and adhesives, so check the exact cassette even after you have the right prefix.

Brother TZe-231 laminated tape
A genuine 12 mm cassette for black text on white laminated labels. Useful when a folder spine, drawer or box face has room for larger type.
Keep in mind. Check that Brother lists the cassette for your P-touch model. Measure the flat space first if you are labelling narrow tabs or dividers.

Check the full code when a listing looks similar
- Read the model code on the printer. Look it up in Brother’s support site and open Consumables & Accessories.
- Read the complete refill code, including its prefix and any final letters. Confirm the width, length, print colour and backing colour match the job.
- Check that the listing’s title, selected variant and packaging describe the same cassette. If you already have a refill, read its code before trying to seat it. If it will not sit flush, stop and recheck compatibility.
TZe-M921 is an example of why the full prefix matters. The cassette belongs to the TZe family and Brother describes it as black print on matt silver. Its compatibility comes from the TZe prefix. Likewise, M-K231BZ and TZe-231 share the number 231, width and colours, so the start of the code is the quickest way to distinguish them. Brother TZe-M921 specification

Common questions
Are Brother TZe and M tape interchangeable?
They are separate cassette families. Check the exact P-touch model and use its supported family. The 12 mm width alone is insufficient to choose a replacement.
What tape fits a Brother PT-M95?
Brother specifies 9 and 12 mm M tape for the PT-M95. One black-on-white option is the genuine Brother M-K231BZ, which is 12 mm wide and 8 m long.
Will M-K231BZ fit the Brother PT-H110?
The PT-H110 uses TZe cassettes. For 12 mm black-on-white laminated tape on that machine, Brother lists TZe-231.
Is the M in TZe-M921 the same as M tape?
The TZe prefix is the cassette family. TZe-M921 is 9 mm TZe laminated tape with black print on matt silver. For an M tape printer, use the model’s M cassette list.
Why does an M-K231 listing show either 4 m or 8 m?
Brother sells the 12 mm M-K231BZ in 8 m and the M-K231SBZ in 4 m. Read the complete code and printed length on the pack before ordering.
