MUNBYN P44S: Setup, Drivers, Ink and Common Problems

Is the MUNBYN P44S right for you?

The P44S is MUNBYN's battery-powered portable 4x6 label printer, intended for sellers who pack orders away from a desk, at markets or in a vehicle. It pairs with a phone over Bluetooth and prints carrier labels from the MUNBYN Print app. It is slower and lighter duty than the desktop RW402B, so it suits occasional use rather than hundreds of labels a day.

Best for: Sellers who need to print shipping labels on the move

Setting up the MUNBYN P44S

Charge the printer fully, install the MUNBYN Print app, and pair inside the app. Feed a stack of fanfold labels print side up and let it learn the label size. Keep print darkness at the default and use quality thermal labels, since portable printheads run cooler and print faint on cheap stock.

1. Unbox and prepare. Remove every piece of shipping tape and packing material, install the ink cartridges, and load paper in the tray.
2. Join your Wi-Fi. Keep the printer close to the router for setup. Most printers only connect to the 2.4GHz band, so if your router broadcasts one merged network name you may need to split the bands temporarily. See our Wi-Fi guide if it will not join.
3. Install the setup app. Use MUNBYN's official app rather than a driver you found on a search result — third-party driver sites are the most common source of printer malware.
4. Add the printer. On Windows 11: Settings › Bluetooth & devices › Printers & scanners › Add device. On macOS: System Settings › Printers & Scanners › Add Printer.
5. Print a test page and run a scan if this is an all-in-one, so you find any problem now rather than when you are in a hurry.

Ink, toner and supplies

The MUNBYN P44S uses the following consumables. Match the number exactly when you buy: the same printer family often uses several different cartridge numbers by region.

• 4x6 direct thermal labels (fanfold)

High-yield (XL) versions almost always cost less per page if you print regularly. On third-party ink and toner, read our honest assessment first, and note that some manufacturers push firmware that rejects non-original chips.
