I'm using the .net sdk and my code seems to be working fine for most of our printers. We have about 25 printers, but with 2 of them I'm getting this error:

Malformed status response - unable to determine printer status

We've tried unplugging the printer and resetting them, but no luck.

The line of code that is getting the error is
var printerStatus = printer.GetCurrentStatus();

Zebra.Sdk.Comm.ConnectionException

Any ideas on what I can look at. I used the code from here as a guide:
