Can I reprint a previously sent job, and how do I check the status of print jobs?

Yes, last printed jobs can be reloaded into HP Click by clicking the 'Add again' functionality in the History section of the Notification Center, though this is supported on select printers only. The Notification Center, accessible via the icon in the top bar, allows you to check the status of documents sent to print, and the application also provides job status information such as Printed, Canceled, or Failed.
