When using ShipRush for USPS printing with a Zebra LP2844
printer, the 2D "Datamatrix" bar code may not print. This is
a crucial issue, as this bar code is the postage stamp!
Note: For questions and technical support related to LP2844 printers and the Datamatrix bar code, please contact Zebra technical support at (877)275-9327. Z-Firm support is not able to assist with printer internals.
Resolution:
In most cases, this issue can be resolved by updating the firmware on the Zebra / Eltron LP2844 printer.
These steps are technical, but any power user or competent
