Fix Adobe PDF Printer Typecheck and Findfont Errors for DWG Files
Question details
The user is experiencing failures when attempting to convert DWG documents to PDF via a virtual printer, specifically encountering PostScript typecheck and findfont errors.

- Product
- Adobe PDF Printer
- Device & OS
- not provided
- Scenario
- Printing or exporting a CAD (DWG) document to a PDF file format.
- Observed behavior
- The printing process is interrupted, and the system generates a PostScript typecheck or findfont error report instead of producing the expected PDF document.
Make sure to save your current CAD work and verify that you have administrative privileges on your computer, as updating printer software or drivers requires admin rights.
Update Adobe Acrobat and Verify File Integrity
Installing the latest updates for Adobe Acrobat DC can resolve known bugs affecting the virtual PDF printer. Testing different files helps isolate the issue.
Software updates often contain patches for PostScript processing errors. Ensuring your PDF printer software is fully up to date is the most critical first step.
Launch Adobe Acrobat DC, click on the 'Help' menu at the top, and select 'About Acrobat' to view your current version.
Go back to the 'Help' menu and click on 'Check for Updates'. Follow the on-screen prompts to download and install any available patches.
Once the update is successfully installed, restart your computer to ensure the Adobe PDF Printer driver is properly refreshed in the system registry.
Open a completely different DWG file in your CAD software and try printing it to PDF to verify if the issue is file-specific or systemic.

Modify Adobe PDF Printer Font Settings
Disabling the 'Rely on system fonts' option forces the Adobe PDF Printer to process document fonts directly, preventing findfont substitution errors.
Manage Standard Documents Effortlessly with WPS Office
While resolving third-party CAD-to-PDF virtual printer errors can be a highly technical process, your daily document management should be simple. WPS Office is a lightweight, fully-featured suite that includes a powerful built-in PDF toolkit, allowing you to easily read, edit, and convert standard office documents without relying on external print drivers.
- 1. Install WPS Office: Download the free installer from the official WPS website and complete the quick installation process.
- 2. Open Your Document: Launch WPS Office and open your Word, Excel, or PowerPoint document.
- 3. Export Directly to PDF: Click on 'Menu', select 'Export to PDF', and save your file seamlessly without encountering PostScript printing errors.

Frequently Asked Questions
What exactly is a PostScript findfont error?
A findfont error occurs when a virtual printer (like Adobe PDF) attempts to process a document containing a specific font that the printer driver cannot locate or substitute properly. This is common when CAD programs use specialized shapes or text.
Why does a typecheck error occur during PDF creation?
A typecheck error happens when the PostScript interpreter receives data in an unexpected format. This is often caused by outdated printer drivers, incompatible graphical elements in the source DWG file, or communication issues between the CAD software and the PDF virtual printer.
Is there a way to convert a DWG to PDF without using Adobe PDF Printer?
Yes. Most modern CAD applications feature built-in 'Export to PDF' or 'Publish' capabilities. Using these native export functions bypasses external virtual printer drivers entirely, which often prevents PostScript errors from occurring.
