Printing Error Error: invalidfont Ricoh Printer

I have a Ricoh Aficio MP 2000 printer. I have macOS Big Sur running on a Mac mini. It is possible to connect to the printer and print graphics, web pages, etc. But I have problems to print PDFs with embedded fonts. I always get Error: invalidfont. I tried the following drivers. - Generic Postscript Printer - Driver provided by Ricoh - Ricoh Printer Drivers v3.0 for macOS What else could I do?
