How to Fix Bulk Portfolio Printing Errors for PDFs
Product
PDF Reader
Device & OS
not provided
Scenario
Attempting to batch print multiple PDF files contained within a single PDF portfolio container.
Observed behavior
The system throws a "Skipped - Not a PDF; cannot print with Adobe" error during bulk printing, although individual files can be printed successfully.
Before you start

Ensure your printer drivers are up to date and verify that all files within the portfolio are actually standard PDF documents, as portfolios can sometimes contain non-PDF file types like Word or Excel documents.

Solution 1Recommended

Extract Files from the Portfolio and Batch Print

Extracting the PDFs from the portfolio wrapper ensures the printer spooler processes them as standard PDF files, bypassing the portfolio compatibility error.

PDF portfolios are essentially containers that hold multiple files. When you send the entire container to the printer, the software may fail to parse the wrapper correctly. Extracting the files to a local folder removes this wrapper.

1
Open the Portfolio

Launch your PDF reader and open the PDF portfolio file that is causing the printing error.

2
Select All Files

Navigate to the portfolio's file list or attachment panel, click on one of the files, and press Ctrl+A (Windows) or Cmd+A (Mac) to select all documents.

3
Extract to a Folder

Right-click the selected files and choose "Extract from Portfolio", or drag and drop the selected files into a newly created folder on your desktop.

4
Batch Print from Windows

Open the folder containing the extracted PDFs, select all of them, right-click, and select "Print" from the context menu to send them directly to your default printer.

Extract Files from the Portfolio and Batch Print
Tip: Printing directly from the file explorer uses your system's default printer settings. Ensure your default printer is configured correctly before batch printing.

Frequently Asked Questions

Why do I get a "Not a PDF" error when printing a portfolio?

PDF portfolios act as a container or "wrapper" that can hold various file types (like Word, Excel, or images) alongside PDFs. If the print spooler or PDF software encounters a non-standard file structure or a non-PDF file within the wrapper during a bulk print command, it triggers this error.

Can I print a PDF portfolio without extracting the files?

It depends on your PDF software. Some advanced PDF readers have a dedicated "Print All" feature for portfolios, but errors are still common depending on how the portfolio was created. If you encounter errors, extracting the files or merging them into a standard PDF is the most reliable workaround.

Are PDF portfolios fully supported in all PDF readers?

No, PDF portfolios are a proprietary feature originally heavily utilized by Adobe. Many third-party PDF readers can only view the cover sheet or allow you to extract the attachments. Standardizing your documents by merging them into a single PDF is recommended for maximum compatibility and easier printing.
