Where this printer fits
E-commerce shipping
For sellers printing carrier 4x6 shipping labels one order at a time, the 2–4 inch print width covers the common label formats and the desktop footprint suits a packing bench or home office.
Warehouse labeling
The 150 mm/s rated speed and continuous thermal printing support picking, packing, and location label runs. Batch throughput depends on your label size and host workflow.
Multi-station setups
USB suits a fixed workstation driving the printer all day; Bluetooth allows sending jobs from a device away from the bench. Confirm your host device and app support before ordering.
What the interfaces are for
USB covers a fixed workstation setup: a packing bench or office desk where one computer drives the printer all day. Bluetooth covers the wireless case, for example sending print jobs from a device away from the bench. The power requirement is 24V/2.5A, so plan a mains outlet at the install point.
Print width vs. paper width
The spec sheet lists two width figures that buyers often compare incorrectly. Paper width (4x6 inch) describes the label stock the printer takes. Print width (2–4 inch) is the range across which the printer can lay down image on that stock. If you plan labels other than 4x6 — for example narrower barcode or address labels — what matters for compatibility is that your label's printable area falls within 2–4 inches, while the stock itself must fit the printer's paper path. Send us your exact label sizes in the inquiry and we will check both figures against them.
Confirm before you order
These items are not stated in the product data, so list them in your inquiry so we can check them against the exact unit you would receive:
- Your label stock: roll core size, outer diameter, and whether labels are fan-fold or roll-fed
- Host system and driver/software compatibility for your OS, including the Bluetooth host device you plan to use
- Print resolution and whether barcode density at 150 mm/s meets your carrier requirements
- Carton dimensions, units per carton, and shipping marks for your market
- Compliance or test documentation required at your destination

Buyer FAQ
Does it print standard 4x6 shipping labels?
The printer is specified for 4x6 inch paper with a 2–4 inch print width range, which is the format used for most carrier shipping labels.
Can I print from a phone or tablet?
The printer has a Bluetooth interface in addition to USB. The specific host devices, app, and driver support are not stated in the product data — confirm your setup in the inquiry.
How fast is a batch of labels?
The rated print speed is 150 mm/s. Actual batch throughput depends on your label size and host workflow, which are not covered by the rated figure.
As a worked example, how many 4x6 labels can it print per minute?
If your 4x6 label prints across its full 6-inch length, 150 mm/s works out to roughly 1 label per second of pure print time, or about 60 labels per minute — an assumption for comparison only, since real throughput also depends on feeding, gaps between labels, and your host software.
What is the minimum order?
Samples of 1–5 units are available; official orders start at 50 pcs. Samples ship in stock, packed the same day.
What power does it need?
The unit uses a 24V/2.5A power supply. Check your local mains voltage requirements for the adapter in your inquiry.
Can I order it under my own brand?
Xiamen Spring Technology welcomes OEM and ODM cooperation. Discuss branding requirements, quantities, and lead times with our team through the inquiry.
