Hello Nina,
Thank you for posting your question on the Microsoft Windows Forum!
Based on your description, these appear to be two separate issues:
- Microsoft Print to PDF is defaulting to Letter-sized output even when the Word document is A4.
- Word's native PDF export is not rendering certain floating images correctly.Since you've already confirmed that:
- The DOCX displays correctly.
- Microsoft Print to PDF preserves the image.
- Word PDF export preserves the paper size.
- The issue is reproducible across multiple documents.
I would recommend troubleshooting each issue independently.
Step 1: Verify Microsoft Print to PDF Paper Size Settings
Although Word shows A4, Microsoft Print to PDF ultimately relies on the printer driver's paper settings.
Open:
Settings
→ Bluetooth & devices
→ Printers & scanners
→ Microsoft Print to PDF
→ Printing preferences
Verify that the default paper size is set to:
A4
Then test a new A4 document.
Also verify that Word's Print screen shows:
Printer: Microsoft Print to PDF
Paper Size: A4
before generating the PDF.
Step 2: Test the Floating Image Layout
Since the image disappears only during Word's PDF export, the issue may be related to the image wrapping method.
Select one of the affected images and temporarily change:
Wrap Text
from a floating layout such as:
In Front of Text
Behind Text
Tight
Through
to:
Square
Then export to PDF again.
If the image appears correctly, the issue is likely related to how Word is processing a specific floating object type during PDF generation.
Step 3: Check Object Anchoring
For one of the affected images:
- Right-click the image.
- Select:
Size and Position
- Verify:
- "Move object with text"
- "Lock anchor"
Temporarily disable custom positioning and test whether the PDF export includes the image.
Step 4: Check Whether the Image Is Linked or Embedded
Go to:
File
→ Info
→ Edit Links to Files
(if available)
Confirm the image is embedded and not linked to an external source.
Linked images sometimes behave differently during export.
Microsoft Documentation
For reference:
- https://support.microsoft.com/office/change-the-size-of-your-paper-in-word
- https://support.microsoft.com/office/wrap-text-around-a-picture-in-word
- https://support.microsoft.com/office/save-or-convert-to-pdf-or-xps
My current suspicion is that the floating-image issue is related to a specific image wrapping/anchoring configuration, while the Print to PDF issue is related to the Microsoft Print to PDF driver's paper-size handling. The results of the image wrapping test should help identify which object property is triggering the PDF export problem.
