How to Fix Adobe PDF Printer Invalidfont Errors in Windows 10
Question details
Users encounter an invalidfont PostScript error and missing font warnings when attempting to print documents to PDF using the Adobe PDF Printer.
- Product
- Adobe Acrobat
- Device & OS
- Windows 10
- Scenario
- Printing documents to PDF from Microsoft Word, Excel, or Outlook using legacy Adobe PDF Printer drivers.
- Observed behavior
- The printing process fails completely, producing no PDF output, while Distiller displays errors indicating missing Segoe UI and Calibri fonts alongside an invalidfont PostScript error.
Verify your current version of Adobe Acrobat, as older legacy versions (such as Acrobat 8) lack native support for modern Windows 10 system fonts and frequently trigger PostScript errors during printing.
Use Native PDF Export Features Instead of Virtual Printers
Bypass the outdated Adobe PDF virtual printer entirely by using the built-in PDF export tools found in modern office software.
Since legacy virtual PDF printers rely on older PostScript rendering engines, they often fail to process newer OpenType and TrueType fonts. Using the application's native PDF export feature avoids the print spooler and prevents font-related conversion errors.
Launch your document in Microsoft Word, Excel, or your preferred office application.
Click on the 'File' tab in the top ribbon and select 'Export' or 'Save As' from the left-hand menu.
Choose 'PDF' as the file format and click 'Save' or 'Publish' to generate the document without relying on the Adobe PDF Printer.
Upgrade to a Modern Version of Adobe Acrobat
Resolve compatibility issues by updating to an Acrobat version that officially supports Windows 10 and modern fonts.

Frequently Asked Questions
Why does Acrobat Distiller report missing fonts like Segoe UI and Calibri?
Older versions of Acrobat Distiller were built before modern TrueType or OpenType fonts like Segoe UI became standard in Windows. The legacy software cannot recognize or process these newer fonts, leading to invalidfont PostScript errors during conversion.
Can I fix the PostScript error without buying a new version of Acrobat?
Yes. Instead of using the Adobe PDF Printer via the 'Print' dialog, you can bypass it entirely by using the native 'Save As PDF' or 'Export to PDF' features available in modern office suites like Microsoft Office or WPS Office.
Is Adobe Acrobat Professional 8 compatible with Windows 10?
No, Adobe Acrobat 8 is a legacy application that is not fully compatible with Windows 10. Using it alongside modern operating systems and office applications frequently results in missing fonts, crashes, and PDF generation failures.
