Sage 500 Error 484 occurred at frmPrintDocuments in Procedure BuildPrintDeviceCombo

SOLVED

Upgrading to Sage 500 7.80.2 on Windows 2016 app server using SQL 2016.  Receive "Error 484 occurred at frmPrintDocuments in Procedure BuildPrintDeviceCombo" when trying to print documents from the 'Edit Shipment' screen, AP checks from the 'Check Printing' screen or just trying to open the 'Set Up Business Forms' screen.  I can still print regular Sage reports (Crystal rpts), where you can select the printer with a regular printer control form.

I suspect this may be some kind of regedit setup issue.  Has anyone else run into this issue?  How to I fix it?
