Apparently this is a partial workaround:
• Change print file output to ZPL
• Use Open-With to open the ZPL with NetSuite Batch File or…
o Associate ZPL file format with the NetSuite Batch File. You may have to make a registry edit so that the ZPL file format is associated permanently (supposedly changing Win10 file association via GUI isn’t permanent so registry hack is required)
• Label printer should then print shipping information.
• Issues that still happen, various reference information may not print on DocTab such as SO#, item #, item weight, etc.,
