LABEL PRINTER - Troubleshooting

Latest Update: 3/8/2011

The Label Printer has several steps for both the installation and configuration, and once installed, is very stable and there are rare issues stemming from configuration.

Nonetheless, certain common problems have arisen, and this article will highlight these issues, and the quickest steps to resolving them:


Printer Settings are not "sticking", and have to be changed every time in order to print correctly. What's wrong?

This problem is common with Windows 7 workstation installations and configuration, and is usually caused by a missed step during the initial setup and configuration of the ZEBRA Label Printer.

In order to remedy this issue, simply go back and follow Step 3 - Configure Installed Label Printer for Window 7 thoroughly, in the HWLP02 - Label Printers - Step-by-Step Configuration Guide.

If, after the above remediation steps have been taken and the issue persists, please contact MJ Freeway Technical Support, and we will be glad to assist.


Printed Labels are not aligned properly and/or the printer feeds an extra label after every print. Can this be fixed?

This problem is common during the initial setup and configuration of the ZEBRA Label Printer, and often times points to an issue with the printer calibration.

Manual calibration is recommended whenever you change label media or if the printer will not correctly auto calibrate. Follow these steps to correctly calibrate your Label Printer:

1. Make sure the printer power is off and that media is loaded.

2. Press and hold the feed button then turn on the printer power.

3. Continue to hold the feed button until the status light LED flashes. Release the feed button.

4. The printer will set the media sensor for the label backing being used. After the printer is done making this adjustment, the roll will automatically feed until a label is positioned at the print head.

5. The configuration settings will print. Upon completion, the printer will save the new settings in memory and remain in diagnostic dump mode.

6. Press the feed button. The printer will dispense another label with the message "Out of DUMP" and be ready for normal operation.

These steps are recommended anytime labels aren't lining up properly or if you have recently changed sizes of label paper. Typically, Zebra printers seem to be shipped with a tiny roll of sample labels that are a different size from what is typically used, so calibrating the printer after putting in the 2"x1" label rolls is a good idea.

If, after the above remediation steps have been taken and the issue persists, please contact MJ Freeway Technical Support, and we will be glad to assist.


Labels are printing "very small" and taking only 60-70% of the label space and will NOT SCAN with the Barcode Scanner. How do I fix this?

This problem is a common issue, often times manifesting itself shortly after the initial configuration of a label printer at a workstation.

It is caused by a primary setting in the Firefox Print Configuration, commonly known as "Shrink to Fit Page", which allows the browser to measure a potential print out against the known size of the paper and its margins, and if necessary, will reduce the print out so that no characters are cut-off. Although this setting is highly beneficial, in general, to ensure that all of your prints are of the whole content that you are viewing in the browser, when you are printing a precise, edge-to-edge style print out, such as a label printer, that setting will often shrink the print out as it is deemed to be precariously close to the edge of the printable area of the target printer/paper.

There are three settings and configurations in the Firefox Print Configuration that must be possibly manipulated to ensure that this problem corrected:

  1. Within the Firefox | Page Setup area, there is a "Shrink to Fit Paper" setting that needs to be unchecked.
  2. If the above does not correct the issues, then check the "Margins & Header/Footer" setting under Firefox | Page Setup (2nd tab) and confirm that it has been setup in accordance to Step 4 - Firefox Print Configuration of the HWLP02 - Label Printers - Step-by-Step Configuration Guide.
  3. Finally, should the problem persist, or return shortly after a few labels are printed correctly, then the default printer under Firefox (not Windows) needs to be changed to reflect the label printer.

You will find that often times, the action taken under the first bullet above will resolve the issue permanently. However, there will be the occasion that due to the distinctiveness of the workstation configuration, the second and third bullets must also be executed.

If, after the above remediation steps have been taken and the issue persists, please contact MJ Freeway Technical Support, and we will be glad to assist.


The ZEBRA Label Printer was printing fine, but now will only print blank pages, or nothing at all. What happened?

Often times the primary cause of this problem is the reset of the Firefox Print Configuration for "Margins & Header/Footer". That could occur due to a Firefox Update, then installation of a new Label Printer, or manual manipulation of the settings for another print out from the browser (which was then never reset).

Simply follow these steps found in the HWLP02 - Label Printers - Step-by-Step Configuration Guide to correctly reconfigure the "Margins & Header/Footer" setting in Firefox:

  • In Firefox, go to File | Page Setup and then the Margins & Header/Footer tab, and ensure that all of the margins are set to 0.0 and all of the headers/footers are set to --blank--. Click Ok to save.

On Mac OS X (10.5.x+), follow these steps to correctly configure the margins in Firefox:

1. Open Firefox, and type about:config in the address bar, and press .

2. Click the button "I'll be careful, I promise." to continue into the configuration area.

3. Type margin into the Filter field to locate the settings for the top/bottom/right/left margins.

4. Ensure that they are all set to 0.0, and once completed, close Firefox.

Go ahead and attempt to print another label, and now it will print correctly to the Label Printer, with the proper output.

There are multiple ZEBRA Label Printers listed in the printer dropdown, and labels don't print to any of them. Why not?

When opening the Windows Printers and Faxes or Devices and Printers window (depending on your version of Windows) from Control Panel or the Start Menu, there are various printers, and at a closer look there are multiple ZEBRA Label Printers, some of which are grayed out.

This problem is due to either having the ZEBRA Label Printer plugged into a USB Hub, or having unplugged and re-plugged in the ZEBRA Label Printer, and changed the USB port. Here is the warning previously posted in the HWLP02 - Label Printers - Step-by-Step Configuration Guide:

Important Note: Whether on a Windows or Mac workstation, it is key that your Label Printer be plugged into an available USB port on the workstation itself and not a USB hub. In addition, should the workstation be moved, or the printer relocated in the workspace, please take care to plug the label printer back into the same USB port as before.

The reason for this, is that the configuration that will be put in place below is very precise, and if the label printer is plugged into another USB port (or on a USB hub), Windows or Mac may install the printer as a new printer, without any of the required configuration settings. Please take note of this requirement, so as to prevent any unwanted issues during checkout.

The corrective steps for this issue are as follows:

  1. Unplug all ZEBRA Label Printers from the workstation, and turn them off.
  2. Uninstall all of the label printers from the Windows computer, by going to the Printers and Faxes or Devices and Printers window (depending on your version of Windows) and right-clicking on each copy of the ZEBRA Label Printer and selecting Uninstall Device or Remove Device.
  3. Once all of the copies of the ZEBRA Label Printer are removed, go ahead and reboot the workstation.
  4. Log back into Windows, and check under Printer and Faxes or Devices and Printers (depending on your version of Windows) that the ZEBRA Label Printer is no longer listed as an available printer after the reboot.
  5. Now, go ahead and turn on and plug in the ZEBRA Label Printer into the workstation. A new ZEBRA Label Printer will show up under the Printer and Faxes/Devices and Printers window.
  6. Go to the HWLP02 - Label Printers - Step-By-Step Configuration Guide and follow the steps as of Step 3 - Configure Installed Label Printer to correctly configure the newly re-installed ZEBRA Label Printer.

That's it! At this point, there is now have a single ZEBRA Label Printer in the workstation, and a label print test can be executed from MJ Freeway.
