Prior to 2021, the T3 T628 was a competent but unremarkable device. It performed its primary function—printing shipping labels, barcodes, and receipts—with adequate speed. However, users frequently reported two persistent frustrations: inconsistent connectivity when switching between USB and Bluetooth interfaces, and a frustrating lag when processing high-density graphics, such as QR codes or complex company logos.
