How do I resolve an HP printer issue where it prints error pages only when printing specific file types (e.g., PDFs)?

If the error occurs only with specific file types, the problem might be with the software used to open that file type (e.g., Adobe Acrobat Reader for PDFs). Ensure you have the latest version of the software installed. Also, try printing the file as an image (e.g., print to a PDF as a JPEG), which can bypass some rendering issues. If the problem persists, consider trying a different PDF viewer.
