Brother ST1150 vs ST1150DX: compare the case and cassette package
The Brother ST1150 and ST1150DX are both discontinued Stanley-branded P-touch label makers in the official U.S. catalogue. The suffix changes the original kit more than the documented printing job: Brother’s exact pages give both models the same QWERTY, laminated-tape, thermal-transfer and 12 mm maximum profile. Their brochures identify the difference that matters when comparing surviving units.
What the original packages add
| Catalogue model | Original brochure contents | Practical distinction |
|---|---|---|
| ST1150 | Labeler, six AAA batteries and one tape cassette | A self-contained keyboard tool; no carrying case is listed. |
| ST1150DX | Labeler, carrying case, six AAA batteries and two tape cassettes | Useful only if the case and extra cassette are present and wanted. |
Brother’s parts reference separately identifies the DX carrying case and cassette pad. That supports a package distinction, not an extra print-width or connectivity capability. Both brochures give the machine itself as 6.1 × 5.1 × 2.5 inches and 0.9 pounds; allow more room for the DX case. An old brochure describes the original box, not the pieces included in a second-hand sale.
Choose by the work, not the suffix
For either model, expect local QWERTY typing, an eight-character single-row display and text up to 55 characters. The shared guide allows two lines only on 9 mm or 12 mm tape, and the two-line print uses Size 1. Brother’s current product pages list TZe tape through 12 mm, while the model-specific guide names Stanley STZ or Brother TZ tape at 6, 9 and 12 mm. The conservative consensus is 6–12 mm; the guide does not settle the current page’s 3.5 mm listing. Check the cassette code before stocking a used unit.
The guide specifies six AAA alkaline batteries or the optional Brother AD-30 adapter. Neither brochure lists the adapter as an included item. The DX is the better package only when its case and second cassette add value; the base ST1150 is simpler if those extras are unnecessary. Choose a different, independently documented model if you need 18 mm media, phone composition, an auto-cutter or a measured print height.
