I did create a folder named gs and put every ghostscript files in the folder.
And when PDFPrinter install, it seems do not know the gs golder and just said ghostscript did not installed and abort install...
Move the files from the GS subfolders LIB, BIN and FONTS to the GS folder. No subfolders should be located in the GS folder. All files must be located directly in the GS folder.
Please read my message again. There should be NO subfolders in the GS folder. Move the files out of the LIB, BIN and FONTS folders and into the GS folder.
