Automatically create PDF

Automatically create PDF

Hi, 

I am trying to automatically generate a PDF of a Custom Record. Ive created a custom record to generate a pseudo Purchase order form. I can download the pdf manually but I am looking for automation in workflow.

Basically, one will fill out the requisite form ive created (step 1). Once its filled out, it will automatically send emails to appropriate people to update the approval status. When this approval status is updated to "approved"(Step 2) . I want to automatically create a PDF of the Custom Record and save this file to a specific folder on my Computer. How can i go about creating this automation?

Thank you for any guidance!
