The Problem was the Airprint connection via WiFi. When Connect with USB problem solved.
In macOS Monterey there is no need for driver because the Printer works via "AirPrint"
Your advice is to print a PDF like a photo ? I accept a solution for the NEW firmware, like adjusting something from Printer's Web Page or a fix, otherwise the downlgrade to previous version works fine.
Thank you for using the Support Forum. If you are using a PS driver please try the PCL driver. If it still fails please see this article about printing PDFs. Please consider contacting your support centre for further assistance.
After update the firmware from V3.50.03.01 to V3.50.03.07 have problem with printing anything from pages to pdf. Works sometime but in most of cases printing 1 page is nightmare.. because I lost more than 10 papers with dots & symbols for 1 page. The only solution I found is to downgrade.
