reload page after pdf download

Question

i am working on a project where department coordinators have to login each and every new job on the portal. where they fill all the information. A job id is generated against the job login.
 
What i want that they could get a job card in pdf format when they submit their job.
After submit button click a pdf should get downloaded and the job login page should get reloaded. So that they could make other entry of other job.
