A: There could be several reasons for this issue.

① Check the print settings.

• Select the correct paper type: If you are printing labels on regular printer paper, you need to select “Plain Paper” under Print Settings → 【Paper Type】 on the 【Print Preview page】. By default, the 【Paper Type】 may be set to “Label Paper,” so if you are using non-label paper for printing, you will need to manually change it to “Plain Paper.”
• Adjust the paper size: Ensure that the paper size in the print settings matches the actual size of the paper being used. If the paper size is set incorrectly, it may result in blank space appearing at the bottom of the printed content.
• Check the print orientation: Incorrect print orientation settings may also result in blank space appearing at the bottom of the printed content. Ensure that the print orientation is set to either “Landscape” or “Portrait” as needed.

② If you are using label paper, check the installation of the label paper.

• Check the installation of the label paper: Ensure that the label paper is correctly installed in the printer without any misalignment or paper jams. Incorrect installation of the label paper may result in blank space appearing at the bottom of the printed content.

③ If you are using label paper, check the printer.

• Clean the printer: If the paper sensor or print head of the printer is dirty, it may cause printing issues. You can use isopropyl alcohol to clean the paper sensor and ensure that the print head is clean.
• Check the printer driver: Ensure that the printer driver is the latest version of the firmware. Outdated or corrupted drivers may cause printing issues. Visit the official website of Fun Print, download, and install the latest driver.

④ Check the print content.

• Check the label content: Before printing the label, check if the label content contains any empty objects or blank characters. These empty objects may cause blank space to appear at the bottom of the printed content.
• Adjust the label layout: Check the layout of the label on the label design page to ensure that the label content does not exceed the valid area. If the label content extends beyond the valid area of the label, it may result in blank space appearing at the bottom of the printed content.

⑤ Other Precautions

• Use the appropriate label paper: Ensure that the label paper used is compatible with the printer. Different types of printers may require different types of label paper.
• Conduct a print test: Before printing in large quantities, print a few samples first to check the print quality and ensure that there are no blank space issues.

If the above methods still fail to resolve the issue, it is recommended to contact the printer’s after-sales customer service and technical support personnel, providing detailed information to obtain further assistance.
