The fastest choice for rugged mobile receipt printing, the PB51 delivers a clear advantage for workers on-the-go who need to produce invoices, delivery receipts, service estimates, mobile point-of-sale receipts, inventory management schedules and sales orders. Whether it is used as a stand-alone printer, or paired with a mobile computer, the PB51 increases operator efficiency. The printer's large memory store reduces system latency and supports fast, high quality production of the graphically complex receipts and invoices that are common in route accounting, transportation and logistics, retail and field service applications. The PB51 printer boasts more than double the memory of competitive models, and features uniquely optimized print mechanisms, enabling it to deliver receipts and invoices 20 to 30% faster while also easily handling complex graphics such as logos. Mil-Spec levels of durability and lightweight design contribute to an overall mobile receipt printing package that delivers measurable improvements in ownership costs and worker productivity. Fast-paced work demands reliability and predictability. With on-board sensors that detect notch, black mark, end-of-roll, and door open status (all communicated via the intuitive LCD display) the PB51 ensures workers always know what's going on with their printer and helps prevent them from losing transactions or wasting time troubleshooting.
