Zebra Link-OS SDK

VB.Net Zebra Link-OS SDK printing Barcodes print fine on my development box. Deployed code throws an Object Reference error when calling the Print method. Used NuGet. Included the support files identified by NuGet.

I am printing cards with Barcodes and without barcodes. The cards without barcodes print fine. The cards that have a barcode throw and Object reference when this line of code is executed.

Dim jobId As Integer = zebraCardPrinter.Print(1, graphicsData)

Cards print fine from my development machine. Compiled code throws the error. My thoughts are a support file may be missing. I included all the NuGet dependencies files.
