Label printer Printronix T8306 300 dpi with RS232 and USB 2.0 interface

Printronix T8306 is a thermal transfer label printer offering 300 dpi (12 dots/mm) print resolution and a maximum print width of 168 mm. It supports roll media up to 172.7 mm wide and a maximum roll diameter of 203 mm. With interfaces including USB 2.0, RS232 and Ethernet, plus 512 MB RAM and 128 MB flash, the unit is intended for reliable label printing in retail, logistics and manufacturing environments and for integration with POS and labeling systems.

Advantages

The thermal transfer mechanism produces high-clarity barcodes and text suitable for shipping labels, inventory tags and product identification. The printer combines multiple connectivity options (USB 2.0, RS232, Ethernet) for flexible integration, and ample memory (512 MB RAM, 128 MB flash) for storing formats and fonts. A maximum print speed of 254 mm/s and support for wide media rolls reduce downtime and increase throughput in high-volume applications.

Suitable for

• Shipping and logistics labels
• Inventory and warehouse tagging
• Retail price tags and product identification
• Integration with POS and label management systems using RS232 or USB

How to use

Install the printer on a stable surface and connect it to power using the included internal power supply and EU power cable. Load thermal transfer media or labels according to the printer’s roll width limits (max. 172.7 mm) and set the correct media type so the Black Mark or Gap Sensor can detect label positions. Connect to a host system via USB 2.0, RS232 or Ethernet and install the appropriate drivers or integrate using your label software. Configure print resolution to 300 dpi and select the required print width up to 168 mm before sending print jobs.

Usage recommendations

For consistent barcode and text quality, use recommended thermal transfer ribbons and label media, verify sensor calibration after media changes, and keep firmware and drivers up to date. If integrating via RS232, confirm serial settings with your host system; for high-volume runs, use Ethernet or USB 2.0 to maximize throughput.
