Compact Thermal Label Printer

The Rongta RP425 is a direct-thermal label printer that produces 4*6 inch shipping labels without ink or toner. It connects via USB or Bluetooth and is controlled through the RONGTA app on iOS, Android, Windows, Mac or Chrome OS. The unit weighs .5 kg and measures 18 cm x 6 cm x 8 cm, making it easy to move between workstations.

Suited For Mobile Shipping Workflows

This printer suits small businesses, home sellers and warehouse staff who need to print up to 60 labels per minute at 127 mm/s. It handles media widths from .98 to 4.37 inches and includes a manual cutter. Buyers who require a built-in automatic cutter, RFID encoding or ribbon-based printing should look at other models.

Build Integration And Space Savings

The RP425 draws power over USB-C and pairs wirelessly, so it needs only a host device and a roll of thermal labels. Its small footprint frees desk space compared with larger desktop units. The package includes the printer, a Type-C adapter, user manual and instruction card for driver installation.

Questions about this item

What type of labels do I need to have on hand before the RP425 can print anything?

The RP425 uses direct thermal 4×6 inch labels, so you must supply compatible label rolls that match the 0.98" to 4.37" width range.

Will the RP425 still pair via Bluetooth with a Mac that has an Intel processor?

The manufacturer notes that macOS Bluetooth pairing is not supported on Intel-based Macs; use the USB connection instead.

How can I confirm the RP425 is printing at the rated 60 labels per minute after setup?

Run a test batch and count the output; the printer should produce up to 60 labels per minute (127 mm/s) when operating normally.
