Hi Richard. Welcome to justanswer.
A PDF file can contain damaged content such as images or fonts that Acrobat cannot process during printing. Printing a PDF file as an image bypasses that processing by sending the printer a simple image of the document instead.
Print the pdf file as an image and then check if it still takes that much time or not.
Hi Richard, how did things turn out?

Choose File > Print, and then click Advanced.
If you don't see the Advanced button, click the Down Arrow (to the right of the Printer pop-up menu).
Select Print as Image
