FAQs

Please read our FAQs page to find out more.

What's the benefit of dual-color printing?

Unlike standard thermal printers that print only in black, the MUNBYN 405B can print in both black& red or black & blue when using compatible dual-color labels. Highlight urgent information, returns, fragile items or promotions without using separate stickers or pre-printed labels.

Do I need ink or toner?

No. The 405B uses direct thermal technology, so there's no ink, toner or ribbons to replace. Simply load thermal labels and start printing.

Can I print normal black labels?

Yes. The 405B works perfectly with standard direct thermal labels as well as MUNBYN dual-color labels, giving you the flexibility to choose the right label for every task.

Who is the 405B best suited for?

The 405B is ideal for Etsy sellers, Shopify stores, online retailers, warehouses, home businesses and anyone who wants labels that are not only professional, but also easier to notice and organize.

What makes the 405B different from other Bluetooth label printers?

Besides fast Bluetooth printing, the MUNBYN 405B offers three standout advantages: dual-color printing, a replaceable print head for longer service life, and a built-in label holder that keeps your workspace neat and efficient.

Why choose dual-color labels instead of normal labels?

Dual-color labels help important information stand out instantly. Whether marking fragile parcels, returns, priority orders or promotional messages, they improve visibility without changing your workflow.

Do I need to buy an external label holder?

Not necessarily. The 405B already includes a built-in label holder, so most users can start printing straight out of the box without purchasing extra accessories.

Why does the 405B have a replaceable print head?

The print head is one of the most heavily used components of any thermal printer. With a replaceable design, you can extend the printer's service life by replacing only the print head instead of the entire machine when needed.

Can I print 4×6 shipping labels?

Yes. The printer supports standard 4" × 6" shipping labels as well as many smaller label sizes for retail, inventory and barcode applications.

Is this printer suitable for daily business use?

Yes. The combination of wireless printing, dual-color labels, a replaceable print head and an integrated label holder makes it well suited for busy online businesses and warehouse operations.
