universal Filter (from cups-filter-core-drivers, v2.0.0-0ubuntu4) Produces Garbled Output when Spoolfile Originates from AdobeReader on Win 10

Problem Description

application//vnd.adobe-reader-postscript input for universal filter is mirrored and scaled down to less than 10% after being converted to PDF output. In the case of the provided example input it happens on page 1, while page 2 looks normal

Steps to reproduce the behavior:

1. Take the attached file d00264-002.
2. Run cupsfilter -p any-valid.ppd d00264-002 > universal-out.pdf
3. Open universal-out.pdf in any PDF viewer of your choice
4. Do you see any content on page 1? How does it compare to page 2?

Expected behavior

A clear and concise image of page content on page 1 similar to the one produced by gs -o ghostscript-out.pdf -sDEVICE=pdfwrite d00264-002

Screenshots

Screenshots from universal's output:

Image 1: Page 1 output scaled down and horizontally mirrored.

Image 2: Page 2 output seems to look normal. Here same zoom level for comparison.

Image 3: Page 1 output by Ghostscript at 100% zoom level.

Image 4: Page 2 output by Ghostscript at 100% zoom level.

System Information:

• OS: [Ubuntu-24.04-LTS]

Additional context
The spoolfile was sent to me by a customer running Linux print servers with lots of different clients (Linux, Windows, macOS). It was retrieved as an example file exhibiting the same problem on various real-life printers.

It is not clear if AdobeReader is the only application which generates printer driver output leading to this problem.

(.txt Suffix added by me, else it wouldn't upload. No suffix originally.)
