Deli E740C Thermal Label Printer

This is a dedicated 4-inch thermal label printer built for high-volume shipping, barcode, and retail tagging. It uses direct thermal technology, meaning no ink or toner is needed, and it churns out labels at a steady 150 mm/s with sharp 203 dpi resolution. The trade-off is that it's a single-purpose machine—USB-only, no wireless, and it won't print standard A4 documents. But if your workflow revolves around barcodes and shipping labels, it's a fast, compact workhorse.
