Hi @Criggypig,

Welcome to the HP Support Community. 

I'd be happy to help you! 

If your HP OfficeJet Pro 7720 printer is producing blurry prints when you change the paper size from A4 to A3, there could be several factors contributing to the issue. Here are some troubleshooting steps you can try:

Check Printer Settings: Ensure that the printer settings are configured correctly for printing on A3 paper. Sometimes, the printer may default to settings optimized for A4 paper, leading to poor print quality on larger paper sizes. You may need to adjust settings such as print quality, paper type, and paper size in the printer driver or control panel.

Paper Quality: Make sure you are using high-quality A3 paper that is compatible with your printer. Low-quality or incompatible paper can cause printing issues such as blurriness or smudging.

Print Resolution: Check the print resolution settings in the printer driver or printing preferences. Increasing the print resolution may improve print quality, especially when printing detailed documents like construction plans.

Printer Maintenance: Perform maintenance tasks such as cleaning the printhead and aligning the cartridges. Accumulated dust or debris on the printhead can affect print quality, particularly on larger paper sizes.

Driver Update: Ensure that you have the latest printer drivers installed on your computer. Outdated drivers may not fully support A3 printing or may contain bugs that affect print quality.

Print Preview: Before printing, use the print preview feature to check how the document will appear on the A3 paper. This can help identify any formatting or scaling issues that may be contributing to the blurriness.

Check PDF Settings: If you are printing a PDF document, check the settings within the PDF viewer or printing dialog. Make sure the document is set to print at the correct size and resolution for A3 paper.

Printer Calibration: Some printers offer calibration options to optimize print quality for specific paper sizes. Consult your printer's user manual or support documentation to see if calibration is available and how to perform it.

If you've tried these troubleshooting steps and are still experiencing blurry prints on A3 paper, it's possible that there may be a hardware issue with the printer, such as a faulty printhead or ink cartridge. In that case, you may need to contact HP phone support for further assistance.

Hope this helps! Keep me posted for further assistance.
