The TSC TTP-247 barcode printer features a clamshell design with a double-layer casing. It comes standard with three communication interfaces: serial port (RS-232C), parallel port, and USB 2.0. Additionally, an optional built-in Ethernet print server is available at an affordable price. The printer utilizes a movable label sensor for easy detection of label positions, accommodating a wide range of media printing needs. Both the printhead and the rubber roller are modularly designed, allowing for easy installation, removal, and maintenance by users. This not only helps maintain good print quality but also effectively extends the machine's service life.
