Sato WS412 Direct Thermal Label Printer

The Sato WD302-400NN-EX1 is a direct thermal barcode and label printer built for point-of-sale environments. It prints at 305 DPI and offers USB, RS232, and LAN connectivity for integration with existing systems. This model suits retailers and logistics teams needing reliable label output without ribbon supplies.

Sustained Load Behaviour

Direct thermal technology eliminates ribbon changes, reducing downtime during continuous print runs. The 305 DPI resolution maintains consistent barcode clarity across high-volume batches. LAN and RS232 interfaces support stable data flow in fixed workstation setups. Buyers needing colour labels or thermal transfer durability should consider alternative print methods.

Questions about this item

How much heat or noise does the WS412 direct thermal engine produce during all-day operation?

The WS412 direct thermal engine has no ribbon motor, so it runs quieter and cooler than thermal-transfer models during continuous printing.

Which cables or host ports must I already have to connect the USB, RS232 and LAN interfaces?

You need a standard USB cable, a DB-9 serial cable for RS232 and an Ethernet patch cable for the LAN port.
