We suggest updating your printer's firmware as this has solved this problem for a number of NRG Customers. When using NRG's UPS Shipping Software with a Zebra ZP-450 ethernet printer, you may experience labels not printing, perhaps due to the printer falling of the network.

Specifically, the ZP-450 is high-performance thermal printer and is commonly used with UPS WorldShip software. NRGship UPS and NRGship UPS Pro support EPL/ZPL printers from Zebra (formerly Eltron).
