MUNBYN P941U USB Label Printer (ITPP941)
The P941U is a plain USB 4x6 printer with two things the Rollo USB lacks on paper: documented gap *and* black-mark sensors, and a 2-year warranty. It is only for computer-based printing—phones are out.
USB-only member of MUNBYN's 941 series; Bluetooth and AirPrint versions are separate products.

Analysis
Desk footprint (approximate)
At 199 × 113 mm (about 7.8 × 4.4 in), plus a 6 in fanfold stack and ~1.5 in paper path behind, plan for roughly 7.8 in wide × 12 in deep. Assumption: stack behind the printer, feeding straight.
Compatibility notes and common mistakes
Install MUNBYN's driver on the computer. For Chromebooks, read MUNBYN's Chromebook help article before buying the USB model.
- Buying the USB model for a phone-first workflow.
- Confusing the P941U with MUNBYN's Bluetooth or AirPrint 941-series variants when ordering.
