Argox D4-250 Pro Direct Thermal Desktop Barcode Printer overview
The Argox D4-250 Pro is a small-footprint 4-inch direct thermal label printer. Its clamshell cover opens fully so media can be dropped in quickly, and its compact body fits on crowded counters and desks.
It prints at 203 dpi and up to 6 ips, with a maximum print width of 108 mm. Ethernet, USB device, USB host and RS-232 are built in, and Wi-Fi or Bluetooth 4.2 can be added as options.
The printer supports Argox's PPLA, PPLB and PPLZ emulations with automatic detection, so it can work with existing label formats. It is the successor to the original D4-250. A 300 dpi version, the D4-350 Pro, is also available.
