Industrial 203 dpi label printer

The Brother TJ-4420TN is an industrial barcode and label printer that supports both direct thermal and thermal transfer printing at 203 dpi resolution. It handles media up to 4.50 inches wide and connects through Ethernet, USB and Serial RS-232 DB9 interfaces. The unit operates on 100-240V 50-60 Hz power and includes a power cord.

Replaces desktop or low-volume printers

This model replaces desktop or low-volume printers when higher daily label throughput and more durable thermal transfer output are required. The jump is worth it for operations that need networked printing across multiple workstations or serial integration with legacy systems. It is not for buyers who need colour output, higher print resolution or mobile battery-powered operation.

Verify media width and interface needs

Confirm that your label stock does not exceed 4.50 inches in width and that your host system can use Ethernet, USB or Serial RS-232 DB9 connectivity. Ensure the application supports direct thermal or thermal transfer modes at 203 dpi. Check that the installation site provides 100-240V 50-60 Hz mains power.

Questions about this item

What is the maximum label width the TJ-4420TN can print?

The printer accepts labels up to 4.50 inches wide, which is the maximum print width for this model.

How do I connect the printer to a network and what step is often missed?

Connect the Ethernet cable to the LAN port, then configure the IP address via the printer menu or web interface; the step often missed is setting a static IP or reserving the DHCP lease so the address does not change after a reboot.

Which consumable parts will need replacement over time on this thermal transfer printer?

The printhead and platen roller are the primary wear items; the printhead should be cleaned regularly and replaced when print quality degrades, while the platen roller needs replacement if it shows cracks, cuts or flat spots that affect media feed.
