Try changing the print settings.....

You don't give us much information to go on, so all we can do is guess at solutions for you. I'm guessing you're ending up with a huge print file, so it takes a long time to get spooled.
If you go into the Advanced button on a PDF print screen that pops up, choose to print as an image. That makes the spooled print job much smaller.
