How to Fix PostScript Syntax Error When Creating a PDF
Question details
The user needs to resolve a syntax error that stops a PDF printer or Acrobat Distiller from generating a PDF file.
- Product
- Adobe Acrobat Distiller / Virtual PDF Printers
- Device & OS
- not provided
- Scenario
- Attempting to create or export a document to PDF format using a PostScript-based virtual PDF printer.
- Observed behavior
- The PDF creation fails completely, often returning a log with an error such as 'OffendingCommand: --nostringval--' due to problematic source content.
Create a backup copy of your original document before you begin deleting or altering elements to troubleshoot the issue.
Isolate and Remove the Problematic Content
Use a process of elimination by printing individual pages and temporarily removing objects to find and fix the data causing the syntax error.
PostScript errors originate from the data generated by the source application. Because PostScript PDF printers stop processing entirely upon encountering an error, you must locate and replace the exact text, font, or image causing the syntax breakdown.
Send individual pages to the PDF printer one at a time to determine exactly which page triggers the PostScript error.
On the problematic page of your backup document, delete elements (such as images, text blocks, or special fonts) one at a time.
Attempt to print the page to PDF after each deletion. If the PDF generates successfully, the last item you removed is the culprit.
Return to your original document, remove the identified problematic element, and insert a fresh copy, a different font, or a flattened image format before exporting to PDF again.
Export to PDF Directly Without PostScript Printers
WPS Office features a built-in, highly compatible PDF conversion engine that doesn't rely on Acrobat Distiller or standard PostScript virtual printers, allowing you to bypass complex PostScript syntax errors entirely.
- 1. Open your document in WPS Office: Launch WPS Office and open the original Word, Excel, or PowerPoint document that was failing to print.
- 2. Access the Export menu: Click on the 'Menu' button located in the top-left corner of the application window.
- 3. Select Export to PDF: Click 'Export to PDF' from the dropdown list to open the conversion dialog.
- 4. Save as PDF: Configure your preferred export settings and click the 'Export to PDF' button to instantly save your file, bypassing the virtual printer completely.
Frequently Asked Questions
What does 'OffendingCommand: --nostringval--' mean?
This is a specific PostScript syntax error indicating that the PDF processor (like Acrobat Distiller) encountered a data string or command from the source file that it could not render. It is typically caused by corrupted fonts, unsupported image compressions, or complex formatting.
Why does my standard printer work, but the PDF printer fails?
Standard physical printers handle data streams differently and may ignore minor errors or substitute missing data to force a physical print. PostScript-based PDF printers require mathematically perfect syntax; any error will instantly stop the entire PDF generation process.
Can I fix a PostScript error without deleting my document's content?
Yes. Instead of permanently deleting the content, you can often fix the issue by changing the font to a standard system font, rasterizing complex vector graphics into flat images (like PNG or JPG), or using a direct 'Export to PDF' feature built into software like WPS Office.
