Can I connect a 3rd party scanner or label printer to the PLT?

Yes!  The PLT has 4 USB ports in the back for accessories like scanners and label printers.  You can buy these accessories from your preferred vendors.  Here are the models we have tested with already:

Zebra Label Printers
GX430t (medium-sized, benchtop)
QLn220 (small, portable)

Zebra Scanners (Barcode Readers)
LS2208, LS4208 (1D scanners)
DS4208, DS6708, DS8108 (2D scanners)

In our own production areas, we typically scan an incoming unit, execute a test plan with the PLT, and then have it print out a serial number label if the tests all pass.  If a test fails, an "NG" label is printed with the test that was failed on it.  This is implemented within the test plan itself.

Integrations with Zebra hardware is outlined in the integrations section:
