It’s not so simple what the other answers are suggesting in fact.

Implementing delayed job for PDF generation is all well and good. But you have more things to consider – you pass the process over to DJ and the end result is a PDF is generated. But you have to then get that PDF back infront of the user – either by polling the job for when it completes and then providing a link to the pdf possibly, or sending them an email to collect the PDF.
