Questions about lossy PDF->PS (Postscript) file conversion

I have an error when converting PDF->PS.

  • Current situation
  • Java Jdk1.8
  • pdfbox-app-2.0.23
    Converting PDF → PS file
    Per-page media tray settings (MediaTray) are not created and lost in PS file

If you are using JAVA for PS file conversion
to convert PS files via Java, we would like to know if there are any other libraries, features or methods that you can refer to.
Also, I would like to set a different media tray for each page I want to print to, do you sell or provide any libraries that allow me to do this, including comprehensive print property settings?

Thank you for reading.
