Adobe Print to PDF invalidfont Error Fix

Who This Affects and What Fixes It

This article is for small-business employees whose Adobe Print to PDF printer creates a text log file instead of a PDF. The log typically contains messages such as “Error: invalidfont” and “No PDF file produced.” This can happen from any application that uses Print to PDF and is often triggered by fonts that Adobe Acrobat does not recognize—such as Aptos. The fix is to adjust a single font-handling setting inside the Adobe PDF printer’s properties.

Why This Matters

Print to PDF is a commonly used feature across many applications. When this error occurs, it can prevent the file from being saved as a PDF entirely—even though the log suggests the printer tried to substitute another font. Correcting the setting below restores normal PDF creation.

How to Fix the Adobe Print to PDF invalidfont Error

Open Printers & Scanners on your computer.
Select and open the Adobe PDF printer.
Open Printer Properties.
Click the Adobe PDF Settings tab.

- If this option was already unchecked when you arrived: check it first, click Apply, then uncheck it again and click Apply. This resets the setting.
Restart any application you were trying to print a PDF from.
Test Print to PDF to confirm a PDF file is now created successfully.

Common questions

Why does Adobe Print to PDF create a .txt log file instead of a PDF?

This happens when the Adobe PDF printer encounters a font it does not recognize—such as Aptos. Instead of producing the PDF, it generates a text log showing errors like “invalidfont” and “No PDF file produced.” Adjusting the font-handling setting in the Adobe PDF printer properties resolves the issue.

Does this problem only happen with certain fonts?

Yes. The error is typically triggered by specific fonts that Adobe Acrobat may not recognize within its own print process. The name of the unrecognized font will usually appear in the log file. The fix described above addresses the problem regardless of which font is causing it.

Will this fix work in any application, or only in certain programs?

The setting change is made at the printer level, so it applies to Print to PDF from any application. Once you update the Adobe PDF printer properties and restart your applications, the fix should take effect everywhere you use Print to PDF.
