Connectivity and software
This refurbished Zebra GC420d is listed for USB use. The GC420d platform provides USB 1.1, RS-232 serial and Centronics parallel ports, so it can also serve older point-of-sale or office hardware. With both ZPL II and EPL2 on board, it accepts label output from courier platforms, e-commerce shipping tools and legacy Zebra or Eltron templates.
Who the GC420d suits
The GC420d is designed for straightforward, everyday desktop labelling. It handles the 100 x 150 mm shipping labels used by most courier and postal services, as well as smaller barcode, address and product labels on rolls up to 127 mm in diameter.
A refurbished Zebra GC420d is a cost-conscious choice for e-commerce sellers, small warehouses and offices adding a second packing station. Direct thermal printing means there are no ribbons to buy or load, and the 32-bit processor keeps label output responsive for daily dispatch runs. Its small footprint also leaves room on the bench for scales, tape dispensers and packing materials.
Setup and care tips
Open the OpenACCESS lid, slide the roll holders apart and place the labels so they feed from the top of the roll, printable side up. Guide the labels out the front, close the lid and press feed. For fan-fold stock, feed it through the rear slot.
Run the auto-calibration after loading a new label type so the sensor locks on to the gap or black mark. Set label size and darkness in the driver before printing a batch.
Clean the printhead with a 99% isopropyl alcohol pen at each roll change. Keep direct thermal labels out of sunlight and heat, which can darken them before they are printed.
