TE Connectivity's T3212 and T3224 are robust 24-hour duty cycle industrial computer-driven 300 dpi or 600 dpi thermal transfer printers. They have been specially designed to print on a wide range of TE labels, cable markers, and identification marker sleeves. They have a full-color touchscreen interface with intuitive icon-based setting adjustments. Various preloaded tutorials answer commonly-asked questions without the unit having to connect to the internet. If, however, an internet connection is required for an application, this can be done wirelessly via a local Wi-Fi network, or via cable; the printers are equipped with USB, Ethernet, and serial ports. Labels or ribbons can also be loaded quickly and easily. Smart print heads have built-in memory to facilitate the maintenance program. This includes the tracking of prints and the printing temperature.
