Printing PDF document with Preview.app in colour, the fonts are blurred.

Dear all,

I have a printing problem and do not know what the cause is.

Initial situation:

- PDF Expert Version 3.9.2 (1038)

- Acrobat Reader 2023.006.20360

- macOS Sonoma 14.4.1

- Printer Ricoh NRG IM C300

Problem:

- When I print the PDF document with Preview.app in colour, the fonts are blurred.

- When I print the PDF document with PDF Expert in colour, the fonts are blurred.

- When I print the same document in black and white, the fonts are sharp.

- When I print the PDF document with Acrobat Reader in colour, the fonts are perfect.

(See picture)

I would like to have the same quality also with Preview.app.

What could be the problem?

I am happy for any advice.

Thank you very much!
