The Smart Label Printer 620 is a versatile and powerful printing device widely used in offices, warehouses, and other settings. However, like any other thermal printing technology, it can sometimes experience issues and fail to print. In this article, we will discuss eight common reasons why a Smart Label Printer 620 may not print and how you can troubleshoot and fix these issues.

8 Reasons Smart Label Printer 620 Will Not Print

Reason #1: Low or empty ink or label roll

One of the most common reasons for a printer not to print is a lack of ink or label roll. To ensure that your printer is working correctly, it’s essential to keep an eye on the ink or single label roll levels and replace them when they are low or empty. To check the ink levels, you can access the ink cartridges by opening the printer’s cover and looking at the level indicator. In case the ink or label roll is empty, replace them with a new one. Make sure you use the recommended type of ink or shipping label roll per the printer’s specifications and ensure they are correctly inserted.

Reason #2: Connectivity issues

Another common reason for a printer not to print is connectivity issues. If the printer is not correctly connected to the computer, it may not be able to communicate with it and print. Ensure that the USB or Ethernet cable is securely attached to the printer and the computer to check for connectivity issues. Also, check that the printer is configured correctly and recognized by the computer. You can check if the computer recognizes the printer by going to the control panel or printer preferences on your computer and see if the printer is listed there. If not, you may have to reinstall the drivers or consult the user manual for further guidance.

Reason #3: Driver or software issues

The Smart Label Printer 620 requires specific drivers and software to work correctly. Ensure that you have installed the latest version of the drivers and software and that they are compatible with your operating system. Sometimes, outdated or incompatible drivers or software can cause issues with printing. You can check for updated drivers on the printer’s manufacturer’s website. Also, you can check for any update in the printer software by going to the printer preferences and checking for updates.

Reason #4: Hardware malfunctions

Sometimes, the printer may not print due to a hardware malfunction. Such issues can range from a faulty print head, card reader, or power supply. In this case, you should contact the manufacturer or a professional technician to troubleshoot and repair the printer. Before you call for support, you can try performing a simple check by doing a print test on the printer. This can help you identify the issue and communicate more effectively with the technician.

Reason #5: Incorrect label or media type

Another essential thing to check is using the correct address label alignment or media for your printer. Some types of brands or media may not be compatible with the Smart 620 – Label Printer and may cause issues with printing the correct label slot. To avoid this, make sure to check the printer’s specifications and use the recommended types of labels or media.

Reason #6: Dirty or clogged print head

Over time, dust, dirt, or other particles can accumulate on the print head, causing it to become dirty or clogged. This can prevent the ink from flowing correctly and result in poor or no print quality. To fix this issue, you can try cleaning the print head with a clean, dry cloth or using a unique cleaning solution recommended by the manufacturer.

Reason #7: Memory or storage issues

The Smart Label Printer 620 may also experience issues related to its memory or storage. This can happen when the printer has too many stored jobs or when its memory becomes full, resulting in the printer being unable to process new print jobs. To fix this issue, you can try clearing the print queue and removing any unnecessary files or stored jobs from the printer’s memory.

Reason #8: Incorrect print settings

Another possible reason for a Smart Label Printer 620 not printing is incorrect print settings. This can happen when the printer is set to print on the wrong type of paper or file folder labels or when the incorrect printing modes or options are selected. To fix this issue, check the printer’s settings and ensure that the correct paper or multipurpose label type, printing modes, and chances are chosen.


In conclusion, a Smart Label Printer 620 can experience a variety of issues that can prevent it from printing correctly. The most common causes of these issues include low or empty ink or label roll, connectivity problems, driver or software issues, hardware malfunctions, and using incorrect sheets of labels or media type. By being aware of these potential issues and taking the appropriate troubleshooting steps, you can quickly and effectively fix any problems with your Smart Label Printer 620.
