Druckprobleme mit InDesign und OKI-C650 auf dem iMac M4

InDesign (and Illustrator) are Postscript-based applications and require a Postscript-capable printer if you want to print directly from InDesign. Any non-Postscript printer will print lower resolution, in which case, the proper approach is to create a PDF (which does the task of converting the file to print properly on other devices). Based on a  quick search, your printer model does have Postscript emulation, so assuming you have installed the proper Postscript driver from OKI for your model and OS (I only see drivers up to OS 15, so if you have Tahoe, you might be out of luck), then you should be fine, ASSUMING you have set the proper options in your Print dialog boxes. So if you can screen shot these, then maybe we can sort out the issues.

In the meantime, your color issues are likely because you are applying double-color management. i.e. you've selected "Let Indesign Determine Colors" unncessarliy because the printer itself alreday has its color management in place. Again, we would need to see your print dialogs.

All this comes down to say, creating a PDF and printing from that is the best approach.

Die Druckertreiber werden nicht oder nicht zeitnah an alle Programme angepasst. Zu Acrobat sind sie jedoch immer kompatibel. 
Deshalb ist es empfehlenswert, die Datei nach PDF exportieren. Die Zeit, die das kostet, holst du wieder rein, weil die Drucker mit PDFs schneller arbeiten. 

Guten tag, Moett,

The correct procedure is to export to PDF; then print from the PDF out of Acrobat. Are you doing this?
