Earlier model comparisons
PT-310B vs PT-D410 vs PT-D460BT: choose by cassette and workflow
These three Brother P-touch models can all print cassette labels, but they belong to different ownership situations. The earlier PT-310B is worth comparing mainly if you already have one or are assessing a particular second-hand unit. Brother’s 2025–2026 replacement-model list names PT-D410 and PT-D460BT as recommended replacements for PT-310B. That is a practical shortlist, not a statement that their cassettes fit the older machine: the current models use TZe and their interface and media evidence must be considered separately.
PT-310B: local typing, but check the cassette twice
The PT-310B brochure describes a 49-key, on-device keyboard, a 15-character LCD, six AA cells and an optional AD-30 adapter. It documents original TZ tape through 18 mm. Brother’s current exact PT310B page also lists TZe through 12 mm, and its current TZeM921 supply compatibility data includes PT-310B. Since the model-specific manual lookup currently errors and the two media records come from different eras, check the cassette family on the actual unit before choosing refills. This is not a phone-app printer and Brother’s FAQ describes a cutter lever, not an automatic cutter.
PT-D410: keyboard or USB-created TZe labels
The PT-D410 review describes a different route: an on-device keyboard plus USB computer connection, with Brother TZe through 18 mm. The D410 includes an AC adapter in its documented package. It is a useful comparison when the typing-at-the-machine convenience still matters but a computer layout route is also needed. It does not make the PT-310B’s original TZ cassettes compatible with TZe, and its USB path still depends on a supported computer and software setup.
PT-D460BT: connected entry as well as a keypad
The PT-D460BT adds app and computer connectivity to its built-in keyboard while staying within TZe widths through 18 mm. Its manual-cut workflow is not an automatic-cutter substitute. If labels are designed on a phone or computer, that extra connection flexibility may be more important than the PT-310B’s historical TZ choice; if direct keypad entry is the main requirement, compare size, display, power and tape access before paying for the connections.
Use the finder’s earlier-model choice only if you want a historical machine included. A hard requirement for original TZ at 18 mm points to the PT-310B’s brochure-backed plan; a hard requirement for TZe at 18 mm points to an exact current-reference model such as the D410 or D460BT, not to a width number copied from the PT-310B’s older brochure. If you cannot verify the cassette family, leave that requirement unresolved rather than assuming the rolls are interchangeable.
