Interface

The printer has two interfaces as standard, parallel and USB. There are no selections to be made, but normally only one interface should be used at a time. The printer may not function properly if data is received on more than one interface at a time.

Caution • Always use Zebra-approved interface cables. Using a non-approved cable with the printer may void the FCC and other EMC approvals of the printer.

Caution • If you connect both parallel and USB cables, the voltage that the host computer outputs on the parallel port may be enough to give signals out on the USB-interface even if the power of the printer is turned OFF!

These signals can result in the operating system of the host computer detecting the printer as on and available when it's not.

Another effect of these false signals is that after turning the printer on and off to clear an error condition, the printer is dead to Windows.

Always disconnect the parallel interface cable when using USB!
