Printing errors of some musical symbols in PDF files created by the Lilypond application.

[French_Tower]

I attach the scan of the prints, where several errors appear.

Unfortunately it seems that it is not possible to attach the original PDF files, which I think would be helpful in diagnosing the problem...

The printer is up to date and it is connected to the home network.

It should not be an operating system related issue, as it occurs when sending documents from other devices.

I also encountered the same problem with another printer, same model. 

I think the printer otf interpreter is making mistakes.

Here's a link with the PDF sources.

Hi @French_Tower,

Thank you so much for the update and for sharing that the issue persists across multiple devices and even with a different printer of the same model.

Recommended Workarounds

Convert PDF to Print-Optimized Format

Before printing, try converting the PDF into a format that's more printer-friendly:

Use Adobe Acrobat Pro or PDF24 Tools to:

"Flatten" the PDF or

Export to an image-based PDF.

This ensures all fonts and glyphs are rasterized or embedded properly, bypassing printer font interpretation.

Print as Image (via Adobe Acrobat)

If you're using Acrobat:

Open the PDF in Adobe Acrobat.

Go to Print > Advanced.

Enable “Print As Image” (choose 300 DPI).

Print the file.

This forces Acrobat to rasterize the content, which avoids font rendering issues at the printer level.

I hope this helps.
