Printer Communication Issues
If the printer is not being recognized, please try the following:
Connection - make sure that the USB cable is firmly connected to the printer and/or try with another USB cable. In case you are using a print server or the printer is being shared from another computer in your local network, please test the printer by connecting it directly to your computer.
- Status Light Indicator - make sure that there is power to the printer and check if the power LED indicator turns on. If the power LED indicator does not turn on, it might be that the power adapter is not supplying power to the printer.
Printer not found - Go to the ‘Printer & Devices’ or ‘Printer & Scanner’ menu of your computer and search for your printer in the list. If your printer is not found, there is an issue with your device. Please try the following:
- Unplug your printer
- (Re)Install the last driver version of your printer
- Restart your computer
You can check the status of the printer in the system settings under Printers & Scanners.
If the printer is showing as offline, click here to see how to set the status to online. Please contact your printer supplier if the problem persists.
Labels not printing
If you are printing a label and the printer is not responding, then the issue might be related to output data or the printer is not receiving the order accordingly. Kindly check the following:
- Not responding errors - is there any error message/code? If the error message makes mention of Sendcloud or our Print Client App, make a screenshot of the error message/code and contact us for further assistance by opening a support ticket from the Sendcloud platform. If the error message is not related to Sendcloud, please contact the manufacturer of the printer for support.
- Status Light indicator - The status of the LED indicator provides the current status of the printer and will help you to identify and correct problems. In some cases the light indicator can be blinking or static in red, blue or orange. Please check the user manual of the printer or contact the manufacturer for further assistance.
- Self-test printing - In some printer models/brands, it is possible to perform a self-test. By performing this test you can isolate the issues related to communication or printing quality, kindly check the user manual of the printer to see if you have this option available.

Labels are blurry or faded
Make sure that there is no dust inside the printer, check the official manufacturer’s site for advice on how to clean the label printer. Try to print any other document or a test page to see if the issue occurs regardless of the document that is being printed.
Bars (in barcode) are very thick
Adjust the print speed and darkness in the settings of the printer, kindly check the user manual of the printer to know more about these adjustments. For more information check the printer preference settings we mention above.
Strange characters when printing
Try to connect the printer using another usb cable, make sure you have installed the latest driver and firmware version available for the model of your label printer. Please note that some manufacturers advise to turn off and disconnect the printer from the computer during a (re)installation. You can also check if the issue persists when you connect the printer to another computer.
Red blocks are printed instead of bar codes
You are probably using a Canon printer. Please download and install the latest printer drivers from the Canon website.

My Zebra printer prints a blank label
There are a number of possible reasons why your Zebra label printer is printing a blank label. A few possible reasons are listed below together with suggested solutions:
Your Zebra printer does not have the right drivers installed for your operating system
First, delete your current printer drivers from the system and later from the Trash bin on your Windows PC. After you've removed your old printer drivers, download the right driver for your printer. Open the Zebra printers overview and choose your printer model. On the support page for your printer model, you can find a list of drivers for various operating systems. Choose the one suitable for your system, click Download, and install the driver.
You have a thermal Zebra printer
This means that your labels should be heat sensitive; however, the ones you are using are not. To test if the labels you are using are heat-sensitive, simply apply some heat to the label. If your labels are heat-sensitive, the area you applied the heat to will turn black. If the label does not turn black, you have non-heat-sensitive labels.
Your printhead needs cleaning
Perform a cleaning procedure on the printhead as described in this Zebra Support article.
Your labels are printing out fine, but the printer is feeding one extra blank label
This can occur for two reasons. The first reason has been mentioned previously - the driver installed is not correct for your operating system. Follow the instructions above to install the right driver. The second reason might be the incorrect printer settings for a Keyboard Display Unit (KDU). If you are not using a KDU, adjust the settings as follows:
Click on Windows [Start] → [Devices and Printers] → Select [Printer Properties] → [General] → [Preferences] → [Advance Setup] → [Miscellaneous] → Untick "KDU Repeat Prompt".
If none of the above has helped, the printer itself might be at fault. Please reach out to Zebra Customer Service to resolve the issue.
Additional Tips and Tricks
After installing a driver or the last version of the Print Client app we recommend you to log out from your SendCloud account, unplug your printer and restart your computer.
By default with some printers, the last version of the driver isn't installed when you plug them for the first time on your computer. We recommend you to visit your printer supplier website to download the last driver version.
If you are experiencing any issue with the size of the printed label, please check our article Printer settings for Windows.
If you are still having issues connecting your printer or printing labels, we advise that you confirm with the manufacturer of your specific printer brand that the printer is working as intended, and that you have installed the latest version of any available drivers.
