Printing Labels Troubleshooting StepsSometimes if you install your ZPL printer directly from Windows, it won't work. If this is your situation (the ZPL won't print), consider the following steps: Start and Stop your Print Spooler under Task Manager > Services. Image ModifiedRight click (or long-press on tablet) and stop, then start this service. Install the ZPL Setup Utility. https://www.zebra.com/us/en/support-downloads/printer-software/printer-setup-utilities.html

In Windows, under Printers, uninstall all unwanted printers from computer (many times, printing issues involve conflicting printer and print drivers).
If Your Printer won’t Print from StratusIf you can print a test label from the Zebra Setup Utility, but not from Stratus Check Windows User Rights: You do not need to run the Stratus Printer app as an administrator, but IT department must not lock down the user profile's write rights to the %appdata% part of the hard drive. Check Firewalls: The Workstation app uses SignalR over port 443, therefore your IT department has to allow websockets via your firewall. If you cannot print with a certain user, troubleshoot by trying to print with a user that has elevated rights on the machine and in Stratus. Try to print a label from a computer NOT connected to your network. If you don’t know how to do this, the GTP SD team can impersonate a user in your company and print to one of their ZPL printers. If they are able to print to a ZPL from Stratus via a user from your company, then there is likely a Windows policy on your computer that prevents the app (via that user) from printing.
