The TSC T4000, from the TSC Printronix Auto ID range, is a compact 4 inch enterprise printer in a steel enclosure with a bifold media door. It prints up to 12 inches per second at 203 dpi, or 10 at 300 dpi.
It supports the major thermal printer languages, takes a 450 metre ribbon and an 8 inch label roll, and can be upgraded with an RFID encoder later.
