Question details
The user needs to resolve an issue where an eight-page PDF document prints the first two pages in A3 size and the rest in A4, alongside a problem with retaining Enter key formatting in text boxes.

- Product
- Adobe Acrobat XI
- Device & OS
- not provided
- Scenario
- Printing a multi-page PDF document that contains mixed page sizes and editing text boxes within the document.
- Observed behavior
- The printer outputs mixed A3 and A4 pages for a single document. Additionally, line breaks created with the Enter key are not retained when formatting text boxes.
Ensure your printer is properly connected, loaded with the correct paper sizes, and that you have the latest printer drivers installed on your computer.
Adjust PDF Print Settings for Uniform Page Sizes
Configure the print settings to ensure uniform page scaling or correctly process native PDF page sizes, depending on your intended output.
PDF documents can contain natively mixed page sizes. If your printer settings are set to follow the document's size dynamically, it will pull both A3 and A4 paper. You can adjust the scaling settings to force all pages onto a single paper size.
Launch your PDF document and navigate to 'File' > 'Print' to open the print configuration window.
Under the 'Page Sizing & Handling' section, select 'Fit' or 'Shrink oversized pages' if you want all pages to print uniformly on A4 paper.
If you intentionally want to print mixed sizes, check the 'Choose paper source by PDF page size' box. Ensure your printer has both A3 and A4 paper trays configured.
Click 'Properties' next to your printer's name and ensure the driver settings are not forcing a specific paper tray that conflicts with your PDF settings.

Troubleshoot Text Box Formatting and Line Breaks
Resolve the issue where Enter key line breaks are not retained by using the correct editing tools and checking document fonts.
Install Latest Software Updates
Software bugs regarding printing sizes or text editing glitches can often be resolved by installing the latest patches for your application.

Frequently Asked Questions
Why does my PDF print in both A3 and A4 sizes automatically?
This happens when the original document contains pages created with different size dimensions. If your print settings have 'Choose paper source by PDF page size' enabled, the printer will automatically switch paper trays to match the native dimensions.
How do I force all pages of a mixed-size PDF to print on A4?
In the Print dialog box, uncheck 'Choose paper source by PDF page size' and select 'Fit' or 'Shrink oversized pages' under the Page Sizing options. This scales A3 pages down to fit standard A4 paper.
Why doesn't the Enter key create a line break in my PDF text boxes?
This can occur due to font embedding issues or using a restrictive comment tool rather than a full editing tool. Ensure you are using the dedicated 'Edit Text & Images' tool so the software processes line breaks natively.
