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.
