Solution 1Recommended

Check and Reinstall the Source Sans Pro Font

Verify if the font is properly installed, remove any corrupted or conflicting versions, and install a fresh copy.

This PostScript error typically occurs when the system cannot find the exact font referenced in the PowerPoint file, or when multiple conflicting versions of the same font are present on the computer.

Open System Fonts

Open the Control Panel on your computer, navigate to Appearance and Personalization, and select Fonts.

2
Locate the Font

Use the search bar in the Fonts folder to look for 'Source Sans Pro Regular'.

3
Delete Conflicting Versions

If multiple versions appear or the font file seems damaged, right-click the font and select 'Delete' to remove them completely.

4
Download and Install

Download a fresh, official copy of the Source Sans Pro font from a reliable source like Google Fonts. Extract the downloaded file, right-click the font file, and select 'Install for all users'.

5
Restart and Test

Restart your PowerPoint application, open your presentation, and try printing to PDF again.

Check and Reinstall the Source Sans Pro Font
Font Name Match: Ensure the installed font name exactly matches 'Source Sans Pro Regular' as requested by the error prompt. Even slight naming variations can cause the PostScript printer to fail.

Frequently Asked Questions

Why do I get a PostScript error when printing to PDF?

PostScript errors during PDF conversion usually happen when the virtual printer cannot interpret a specific element in the document. This is most commonly caused by an embedded or system font that is missing, corrupted, or restricted by licensing.

Can I embed fonts in my PowerPoint to avoid this error?

Yes. In Microsoft PowerPoint, go to File > Options > Save, and check 'Embed fonts in the file'. This ensures the exact font data travels with the document, which often helps prevent missing font errors when sending the file to print or PDF.

What if I cannot install the Source Sans Pro font on my computer?

If you lack installation rights or prefer not to install new fonts, you can replace the missing font with a widely available system font like Arial or Calibri. Use the 'Replace Fonts' feature in your presentation software to update the document before printing.
