Choose the supply family first, then a width accepted by your printer. Only after those checks should you choose colour, adhesive, finish and pack quantity.
A genuine tape from the correct brand can still be wrong for the machine. Brother’s PT-D210 stops at 12 mm, while the PT-D610BT accepts TZe tape up to 24 mm.
Cassette family, width and material answer different questions
The family identifies the physical supply system. Width determines whether that size is accepted. Material determines whether the label is suitable for its surface and use.
For example, DYMO 91331 is white plastic LetraTag tape. DYMO 45013 is black-on-white D1 tape. They are both nominally half an inch wide, but they are intended for different cassette systems.
| Check | Example | Decision |
|---|---|---|
| System | TZe, D1, LT or M21 | Use the system named for the exact machine. |
| Width | 12 mm versus 24 mm | Stay within the machine’s listed widths. |
| Material | Paper, plastic, nylon or heat-shrink sleeve | Choose for the application; these are not cosmetic options. |
Compare complete references
Keep every letter and suffix in the item code. A strong-adhesive or flexible reference is a separate product from standard tape of the same colour. A multi-pack can also contain several sizes or materials.
For roll-fed printers, replace the cassette-family check with print technology and media dimensions. Colour is still a later choice.
