If you’re choosing a label printer for Etsy, eBay, or Shopify shipping, the Rollo Wireless X1040 and the MUNBYN RealWriter 403B are two of the most popular 4×6 direct-thermal models. Both are fast, inkless, and affordable compared with enterprise gear, but they’re aimed at slightly different users. The Rollo Wireless X1040 emphasizes true cable-free printing—including certified Apple AirPrint—so you can print directly from iPhone or iPad without drivers. The MUNBYN 403B leans value-first, offering Bluetooth and USB connectivity with a friendly mobile app and plenty of community buzz. If you need dead-simple wireless from any device, Rollo is compelling; if you want maximum bang-for-buck with flexible accessories, MUNBYN is hard to ignore.

Design & Setup
Rollo Wireless X1040 is built for minimal friction in mixed-device environments. Because it’s AirPrint-certified, iPhone and iPad users can print labels natively from supported apps—no drivers or special utilities required. Wi-Fi setup is straightforward, and Rollo pushes over-the-air updates, so firmware and features improve without you touching a USB cable. In practical terms, if your household or small office uses a mix of iOS, macOS, and Windows, Rollo’s “just works” factor is a time saver.
MUNBYN 403B focuses on approachable setup with Bluetooth for phones/tablets and USB for desktops. MUNBYN’s Print app and Editor software provide ready-made templates and a guided first-run experience. The chassis is compact; some bundles omit a built-in roll holder (you can add an inexpensive external holder), which keeps the price attractive. For first-time thermal users who want to be up and running quickly, it nails the basics.
Features
Rollo’s headline feature is native AirPrint on top of Wi-Fi, which means true driver-free printing from iOS/iPadOS and easy sharing on your network. Auto label detection streamlines switching between 4×6 and other sizes, and the device is tuned for common marketplace workflows. If you routinely print from an iPhone or iPad—or you hand a packing iPad to a helper—this simplicity matters.
MUNBYN counters with a surprisingly rich software/app ecosystem for the price: Bluetooth printing, a template library with thousands of elements, and straightforward tools for shipping labels, stickers, and barcodes. While the 403B is 203 dpi, MUNBYN’s broader lineup includes 300-dpi models for tiny QR codes—useful context if your labels are extremely dense. If you like tweaking templates or printing the occasional small logo, the MUNBYN toolset is friendly.
Performance
Both printers are quick enough for busy micro-shops, but Rollo has the cleaner path to one-label-per-second throughput: the X1040’s spec is 150 mm/s, which translates to roughly one 4×6 every second once your workflow is dialed. Wireless performance is consistent, and AirPrint avoids driver bottlenecks on iOS.
MUNBYN’s RW403B holds its own: recent hands-on testing measured ~72 labels/min, lining up with ~150 mm/s class speeds in real-world batches. print quality at 203 dpi is perfectly fine for shipping barcodes and standard graphics; if you plan to pack micro-QRs or tiny fonts on small stickers, you’ll want to step up to a 300-dpi variant (a different MUNBYN model).
Costs
Both are direct-thermal printers, so there’s no ink or toner—you’ll only buy thermal labels. That’s the biggest long-term cost advantage versus inkjet/laser. Neither model forces you into proprietary labels, so you can shop for generic 4×6 fanfolds or rolls to keep per-label costs low. Rollo’s X1040 hardware typically prices above MUNBYN’s 403B because of Wi-Fi + AirPrint and its polished wireless stack; MUNBYN often undercuts Rollo on initial purchase while delivering similar day-to-day shipping performance.
Consumables are comparable: standard 4×6 direct-thermal labels are widely available, and both printers can chew through them quickly. If you need a roll holder for MUNBYN (some kits lack one), budget a little extra; it’s a one-time add-on that also improves feed reliability for large batches.
Verdict
Winner: Rollo Wireless X1040 for its best-in-class wireless experience (true AirPrint + Wi-Fi) and “it just works” setup across iPhone, iPad, Mac, and PC. Pick MUNBYN 403B if you want the best value in a capable shipping label printer with Bluetooth/USB, friendly apps, and strong real-world speed—and you don’t specifically need AirPrint.
FAQ
- Is either printer truly “inkless”?
- Yes. Both are direct-thermal printers. They heat special media to form text and barcodes, so there’s no ink or toner to replace—just labels.
- Can I print from an iPhone or iPad?
- Yes—with differences. Rollo Wireless X1040 is Apple AirPrint-certified, so you can print natively from iOS/iPadOS apps. MUNBYN 403B supports Bluetooth printing via the MUNBYN app; it’s not AirPrint, but it’s easy for common workflows.
- Which one is faster?
- On paper, both operate in the ~150 mm/s class; Rollo explicitly specs 150 mm/s, while third-party testing of the 403B shows ~72 labels/min, which is effectively similar for 4×6 shipping labels. Your real-world speed will depend on your device, network, and batch size.
