Common Configuration Problems

If your the ZPL won't print, consider the following steps:

  1. Make sure in Windows Settings Printers, that your ZPL is your default printer (go to step Default Printer Step 4 below)

  2. If you installed your ZPL printer directly from Windows, it won't work. In that case, uninstall and reinstall as per the following steps.

  3. Reinstall as Needed

    1. Start and Stop your Print Spooler under Task Manager > Services.

      image-20240521-142317.png

    2. Right click (or long-press on tablet) and stop, then start this service.

    3. Install the ZPL Setup Utility. Zebra Printer Setup Utilities | Zebra

      image-20241022-140542.png

    4. Install your ZPL printer drives from the Zebra Setup Utility.

      1. In Windows under Printers (see image below):

      2. Uninstall your ZPL printer.

      3. Then, using the Zebra Setup Utility, reinstall your printer.

Set as Default Printer

  1. Set Default Printer

    1. Set your ZPL printer as the default printer.

 

image-20240521-142018.png

 

d. In Windows 11:

"Let Windows manage my default printer" is ON.
Turn off (or toggle off) the setting "Let Windows manage my default printer".

  1. In Windows, under Printers, uninstall all unwanted printers from computer (many times, printing issues involve conflicting printer and print drivers).

  2. Print a test page from Windows (if that works, try from the Stratus Printer App as well)

It Prints, but not from the Stratus Printer App

If you can print a test label from the Zebra Setup Utility, but not from the Stratus Printer App

  1. Verify that you have the latest version of the Stratus Printer App installed.

    1. To see a list of available versions from GTP, run this command from a command prompt – i.e., type CMD into the Windows search bar, run that, then type in the following command:

      winget show GTPSoftware.Print -s GtpSoftware --versions

    2. Compare this to the version of your Printer app.

  2. Verify that the Stratus Print application is open.

  3. Verify that the printer is not asleep.

  4. Verify the computer has a station assigned to it if attempting to print from a station.

  5. Read the LOG file generated by the Stratus Print app.

    1. Exit the Stratus Print app first (so that it will flush its remaining log entries),

    2. then go to
      C:\Users\<Windows User>\AppData\Roaming\GTP STRATUS Logs\Print\

    3. See the Log.Txt file in that folder.

    4. Open with notepad or some other tool.

      1. Note well: The newest activity is at the bottom (the oldest log activity is at the top).

    5. From top down, search for the word “Error” or “Warn”

  6. 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. 

  7. Check Firewalls: The Workstation app uses SignalR over port 443, therefore your IT department has to allow websockets via your firewall.

  8. 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.

  9. 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.

  10. If you still have no success, send the log file from Step 1 above to the GTP Service Desk
