When I print the document in colour, the fonts are blurred.

Dear all,

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

Initial situation:
- Affinity Publisher 2.2.1
- and also Apple Pages 13.2
- macOS Ventura 13.5.2
- Printer Ricoh NRG IM C300

Problem:
- When I print the document in colour, the fonts are blurred.
- When I print the same document in black and white, the fonts are sharp.
- The problem occurs with Affinity Publisher as well as with Apple Pages.

What could be the problem?
I am happy for any advice.

Thank you very much!

Hello,
Perhaps the printer driver has not noted that in color mode the printer would use only black toner as black color, not the CMYK combination?
