1. Clear browser cache and data

Corrupt or expired browser cache files may cause page content to not render properly, especially when printing operations are performed. Clearing the cache forces the browser to reload the page resources, helping to resolve preview blank issues.

1. Open UC browser and click "My" in the lower right corner to enter the personal center.

2. Click the menu icon in the upper left corner and select the "Settings" option.

3. Enter the "Clean Browser Cache" function and confirm that all cached files and offline data are cleaned.

4. Restart UC browser and reload the web page you need to print, and try printing the preview again.

2. Check the printing settings and paper configuration

Incorrect printing settings, such as selecting a mismatched paper size or enabling the option to hide background content, can cause the actual content to not be displayed in the preview. Ensuring that the settings match the document content and the physical printer is a key step.

1. Click the "Share" button on the web page and select the "Print" function to enter the preview interface.

2. Click "Settings" or "More Options" in the preview interface.

3. Check whether the paper size is A4 or other common specifications, and make sure the direction (vertical/horizontal) is correct.

4. Turn off options such as "Print text only" or "Hide background graphics" that may filter content.

3. Save the web page as PDF and print it

Printing web pages directly is susceptible to format compatibility, while generating PDF files can solidify the page layout and avoid blank previews caused by failed dynamic content loading. This is an effective way to bypass browser native printing defects.

1. Open the landing page in UC browser and click the "Share" menu.

2. Select the "Save as PDF" or "Export as PDF" function (if there is no such option, you can use the system-level "Print" function and select "Save as PDF").

3. Save PDF files to your mobile phone storage and open the file using applications such as WPS Office or Adobe Acrobat.

4. Call the printing function in the PDF reader to see if the preview displays the content normally.

4. Change the browser or use desktop mode

The mobile version of UC browser may have defects in printing function compatibility. Switching to other mainstream browsers or enabling desktop web mode can improve page rendering integrity and improve print preview effects.

1. Click the "..." menu on the right side of the address bar in UC browser and select the "Desktop Website" option to load the complete web page structure.

2. After refreshing the page, try printing the preview again.

3. If the problem remains the same, it is recommended to install Chrome or Edge browser and use its built-in printing function to test the same web page.

4. Compare the preview results of different browsers and confirm whether it is a UC browser-specific fault.
