• Versatile printing methods — The WPL308 supports both direct thermal and thermal transfer printing, enabling you to choose the most cost-effective solution for your labeling needs. Direct thermal printing eliminates the need for ink or toner, while thermal transfer delivers durable, long-lasting labels suitable for harsh environments. This flexibility allows you to print onto a wide range of label materials, from standard paper stock to synthetic, weather-resistant ribbons, ensuring your labels withstand handling, moisture, and temperature variations.
• Intuitive user interface — A 3.5-inch color TFT display with a real-time clock puts essential information at your fingertips. The display enables simple navigation through print settings, media calibration, and diagnostic messages, so operators can quickly adjust label dimensions, print speed, darkness, and ribbon settings. This user-friendly interface minimizes setup time and reduces operator errors, speeding up daily labeling tasks.
• Robust design for easy maintenance — The WPL308 features a double-wall clamshell design that makes media loading, ribbon changes, and routine maintenance straightforward. The top-access design reduces the need to handle the printer from awkward angles, while a sturdy chassis helps resist vibration in busy work environments. The result is smoother operation, less downtime, and improved longevity for demanding labeling workloads.
• Flexible connectivity options — With USB and Serial (RS-232) interfaces, the WPL308 integrates easily with a wide range of point-of-sale systems, label design software, and enterprise workflows. Whether you’re connecting to legacy systems via serial or modern PCs via USB, you can rely on stable data transfer and quick print initiation. The flexible interfaces also enable simple daisy-chaining or network configurations through compatible devices when required.
• High-contrast, monochrome label output — The WPL308 delivers crisp, legible monochrome prints that are ideal for barcodes and human-readable text. The monochrome output ensures strong scan reliability and consistent readability across different label materials and printers, helping to reduce misreads and improve overall inventory accuracy and traceability.

How to Install Wasp WPL308

• Unpack and inspect the printer and accessories to ensure all components are present. Remove protective packaging and position the printer on a stable, clean surface near your workstation or label workflow.
• Choose your connection method. If you’re using a modern computer, connect the WPL308 via USB for straightforward driver installation. If you’re integrating with an older system, you can use the Serial (RS-232) interface. Ensure the chosen interface matches the port available on your computer or controller.
• Install the printer driver. Visit the manufacturer’s website or use the provided driver CD to install the appropriate driver for your operating system. Follow the on-screen prompts to complete the installation and restart your computer if required.
• Load media and ribbon (if using thermal transfer). Open the clamshell, place the label roll onto the supply spindle, thread the label path through the media sensor, and close the lid. If using thermal transfer, install the ribbon correctly with both supply and take-up reels aligned. Calibrate the printer to the correct media width and gap/mark position using the 3.5-inch color TFT display.
• Configure print settings. Use the on-device display to set label width, media type, print speed, and darkness. If your software requires specific label templates or barcode symbologies, configure these settings within your label design software or via the printer driver to ensure compatibility with your labeling requirements.
• Perform a test print. Print a simple label to verify alignment, barcodes, and text quality. Make any micro-adjustments to margins or darkness until the output meets your quality standards. Verify scan reliability with your barcode scanner to ensure consistent readability across labels.
• Integrate into your workflow. Once printing is tested, create templates for common labels, automate label generation through your ERP or inventory software, and establish a routine maintenance schedule to keep print heads, sensors, and media guides clean and calibrated.
