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.
