Compare a Bluetooth-and-USB 300 dpi printer with a Wi-Fi and AirPrint 203 dpi printer, both for generic direct-thermal labels.
The decision in brief
How the options differ
Both accept compatible direct-thermal labels without a brand-only rule, so the decision is mostly about how jobs reach the printer. MUNBYN documents Bluetooth through its app plus USB; Rollo documents Wi-Fi with AirPrint plus USB fallback. MUNBYN's own page also gives conflicting speed and label-width figures.

The buying guide
Package and specification details
Bluetooth is not Wi-Fi
The 941BP pairs by Bluetooth with the MUNBYN Print app on iPhone, iPad and Android, and with Windows; Macs connect by USB. Rollo Wireless joins a Wi-Fi network and documents AirPrint, with USB as a fallback. If printing must go over a shared Wi-Fi network, only the Rollo evidence documents that path; the 941BP evidence does not establish Wi-Fi.
MUNBYN lists 300 dpi and Rollo 203 dpi. A higher nominal resolution can matter for small text and dense codes, but it does not prove a scannable label; artwork, scaling and media also matter. Print a test label from your carrier before relying on either.
The 941BP page says up to 180 mm/s in one section and 150 mm/s in its table and FAQ, and gives label widths of 40-104 mm and 40-110 mm. Rollo advertises up to 150 mm/s. Treat all of these as feed-speed claims, not job times, and check your label width against both MUNBYN figures.
No automatic cutter is documented for the 941BP, and the reviewed Rollo offer describes tear-off handling. Plan for manual separation with either printer.
MUNBYN shows two different box lists; one adds Type-C and USB cables and a flash drive. Rollo documents a USB fallback cable. Check what arrives before planning a wired setup.

Printing method
The documented process for this printer.
Direct-thermal printers use compatible heat-sensitive labels, not ordinary uncoated paper; no ink cartridge does not mean no consumables.

Nominal resolution
The base resolution documented for ordinary printing.
Resolution alone does not establish barcode readability or measured quality. Artwork, scaling, media and settings also matter.

Label format and width
The supported shipping-label format, with print width distinguished from media width.

Four-by-six shipping labels and narrower labels are described, but the page gives two label-width ranges: 1.57 to 4.3 in (40-104 mm) in the description and 40-110 mm in the specification table and FAQ.
