Compact Thermal Label Printer

The Rongta RP425 is a direct thermal label printer that produces 4x6 inch shipping labels and smaller formats up to 4.37 inches wide. It connects via USB or Bluetooth to Windows 7 and newer, macOS 10.11 and newer, Chrome OS, iOS and Android devices using the RONGTA app. The unit weighs .65 kilograms and measures 10.24 x 7.4 x 5.3 inches.

Small Business Shippers and Mobile Workers

This printer suits sellers who need fast 150 mm/s output for packing slips, barcode tags or QR code labels without ink or toner. Buyers who require colour printing, ribbon-based media or network Ethernet connectivity should look at other product types.

Desk-Friendly Build for Mixed Environments

The compact footprint fits on a crowded bench or in a drawer and the Bluetooth link removes a cable run to a phone or tablet. USB provides a wired fallback for desktop workstations. Direct thermal media eliminates ribbon stock, freeing storage space for label rolls.

Questions about this item

Which devices and operating systems can I print from using the RP425's Bluetooth connection?

The RP425 connects via Bluetooth to iOS and Android phones or tablets through the RONGTA app, and it also supports USB printing from Windows 7 or newer, macOS 10.11 or newer, and Chrome OS.

Will my existing rolls of direct thermal labels work with the RP425's automatic identification feature?

The RP425 automatically detects and feeds any direct thermal labels between 0.98 inches and 4.37 inches wide, covering standard 4x6 inch shipping labels as well as smaller barcode, QR code, and circular label sizes.

How can I confirm the RP425 is printing correctly after I set it up?

Print a test label at the rated 203 dpi resolution and up to 150 mm/s speed; the output should show sharp, smudge-free text and barcodes on direct thermal media without any ribbon or ink required.
