Will a large quantity of high resolution files (15MB+) that are linked through InDesign ultimately result in slower processing of the document? Or create too large post script files when printing? I'm trying to convey a message that there is no need to link high res files that hugely exceed the needed resolution for printing or exporting.
I wouldn’t worry about it for exporting and I would never print from InDesign especially to postscript.
Export a PDF and print that.
