• Fast direct thermal printing up to 5 inches per second: time is money in busy operations, and the RJ4040’s speed ensures you don’t bottleneck lines or service calls. Direct thermal technology means no ink or toner to manage, reducing maintenance and consumable costs. Quick print throughput helps you generate receipts for customers and labels for parcels, pallets, or asset tracking in seconds. Crisp, high-contrast monochrome output enhances readability, improving accuracy in inventory checks and reducing the chance of misreads during audits or scans.
• Versatile media support for receipts and labels up to 4 inches wide: switch between media types without swapping devices. The RJ4040 handles common label formats and POS receipts, helping you consolidate equipment and simplify operations. This flexibility is particularly valuable in retail backrooms, courier hubs, and field service, where you might need to issue a receipt to a customer one moment and print a shipping label the next. The smooth media path and reliable feed system minimize jams and misfeeds, even with heavier label stock.
• Comprehensive connectivity: USB, Serial, and Wireless LAN with battery included: stay connected to laptops, tablets, or mobile devices across different work scenarios. USB and Serial interfaces provide compatibility with a wide range of legacy systems, while Wireless LAN enables seamless wireless printing from modern devices and cloud-based workflows. The built-in battery keeps the RJ4040 operational away from power outlets, supporting multi-shift work and remote job sites. With all these options, you can integrate mobile printing into existing IT ecosystems without disruptive changes.
• Certified ruggedness: IP54 protection and 6 ft drop performance: designed to endure dust, moisture exposure, and occasional accidental drops, the RJ4040 is a dependable choice for environments like warehouses, delivery yards, and outdoor job sites. The IP54 rating ensures durability against water and dust ingress, while the 6-foot drop tolerance minimizes downtime from everyday accidents. These rugged features translate into higher uptime, lower maintenance costs, and greater confidence in printing during critical operations.
