Unable to print from Desktop client

One cause for this issue was the Firewall blocking the Port on the server.

To overcome the issue, I went into the firewall settings and added a rule to allow inbound communication on the port (2077).

Label not printing

When printing labels and everything "works" except for label not printing.

Test by supplying a printername and not leaving empty or depending on default. This might be one reason, the other seems to have something to do with license server. It might be combination where it does not allow because the allocated license and the printername does not "match", note this is on Bartender SDK level.

Other issues and Object reference not set

You might have to also copy the dll's in directory (C:\Program Files (x86)\Seagull\BarTender Suite\SDK\Assemblies\.*) from the PC to the directory of the Granite label printing service.
Ensure the dll's in the directory is not blocked by windows. Right click and select Properties if you see a button [Unlock], the dll's are blocked, one by one unblock all.
