I would like to know where the setting is to set the correct colours when printing a rasterized PDF?

Greetings everyone,

I have a user who want to print a PDF with material displayed and the printer changes the setting to rasterized. See attached PDF RATERIZED AND INCORRECT LINE COLOUR (site cadastral showing green). When I print to PDF all my pen colours change. They sPDFPDFhould look like this PDF NOT RATERIZED AND CORRECT LINE COLOUR (site cadastral showing black).
