Product Overview
The SATO WD312-400NW-EX1 is a WS412 desktop direct thermal label printer with a 305 dpi printhead and Wi-Fi alongside its wired ports. It prints a 4-inch wide label and handles shipping labels, small-part labels, dense 2D codes and product labels. Wireless connectivity lets it be placed where running a network cable is impractical. Tech Seller USA supplies this part in tested and verified refurbished condition, for single units or volume orders.
Key Specifications
Printing is direct thermal at 305 dpi, with a print speed of 4 ips and a maximum print width of 4.1 in. Connectivity is USB, serial (RS-232), Ethernet and Wi-Fi. Media is label stock on a 1.0 in or 1.5 in core, up to a 5 in maximum roll diameter. Remaining specifications vary by configuration and are confirmed on the actual unit before dispatch.

Compatibility & Use Case
It suits a counter, mobile cart or satellite bench that needs fine 305 dpi output over a wireless connection. It is supplied as a like-for-like replacement where a WS412 is already in service and the label stock, drivers and label formats are staying the same.
