I printed a document to a pdf and the size came in as 168,000 KB, this is too large to email. Is there a way to compress this file before emailing it, or printing it to a smaller size file?

When queuing to print to a pdf, I am getting the message "It says a script on the page is busy or has stopped responding." I am using the lastest version of firefox, and de-installed, re-installed, there is nothing in my printer queue. Any suggestions?
