Brother TD4420TNP 4.3" Desktop Thermal Transfer Label Printer
Overview
The Brother TD4420TNP is a compact 4.3-inch desktop thermal transfer printer delivering 203 dpi resolution at 6 inches per second. Built for on-demand label, wristband, and receipt production in warehouse, logistics, and point-of-service environments, it handles label media from 0.79 to 4.65 inches wide and supports roll stock up to 5 inches outside diameter. The integrated peeler automates label removal in high-volume operations, and direct thermal print technology ensures durable output on synthetic substrates and coated label stock without requiring ribbon.
Connectivity & Integration
The TD4420TNP connects via USB, Serial, and Ethernet LAN—enabling integration into networked warehouse management systems, point-of-sale platforms, or standalone desktop workflows. It supports Windows, Mac, and Linux print drivers. The printer interprets ZPL II, CPCL, Raster Graphics, Text Template, and ESC/P command sets, so migration from competitor desktop printers carries minimal configuration burden. Memory includes 128 MB Flash and 64 MB SDRAM (40 MB allocated for templates and databases), sufficient for storing label layouts and product databases without external storage dependencies.
Media & Output Specifications
Maximum print width is 4.25 inches, accommodating 4-inch label stock with margins. Media feed is drop-in roll format with adjustable roll holder and external slot support. The peeler supports automated removal; alternatively, use tear-up media exit for manual stripping. Media sensors include transmissive (gap/hole detection) and reflective (black-bar, hole) modes, plus out-of-paper and peeler status sensing. The printer encodes 2D barcodes including QR, Data Matrix, PDF417, Aztec, and Maxicode natively.
Physical & Environmental
Dimensions are 8.1 × 7.0 × 11.1 inches; unit weight is 4.4 lbs (2 kg) without media. User interface consists of one feed/print button switch and one LED for power, end-of-roll, and status indication. The TD4420TNP carries a 2-year manufacturer warranty.
