Every time you successfully print a job, the content of the print job (i.e. the document) gets deleted from our server or if the job is QUEUED or in ERROR state for more than 30days, the content will be deleted at that time. However, the name of your print job, and some other metadata associated with the job (like time it was printed) remains in our server.
We currently don't have any UI that allows you to select multiple print jobs at once for deletion, but you can use our HTTP API to achieve the desired effect. Specifically the /jobs and /deletejob APIs.
