Zebra 2844 stays asleep after waking computer--must unplug to start

SOURCE: Zebra LP 2844 printer will not print anything but the test page

possibly not a real LP2844 but an LP2543, a printer mass produced for and used by UPS. refurbishers change the label and sell as LP2844 because they are almost identical.
if it has an AC-AC adapter, it is an LP2543. LP2844 uses a AC-DC adapter, and all LP2844's have USB ports.

when submitting the print, un-tick the collate box. Use the properties section to check the speed settings in the driver and try again
