A method of handling a document stored in a cloud storage system, in which a user is identified by first user credentials, for processing by an authenticated printing system for which said user is identified by second user credentials, comprising the steps of
- i. obtaining said document from said cloud storage, said first user credentials being associated with said document,
- ii. obtaining said second user credentials based on said first user credentials, wherein said second user credentials are obtained by contacting the user using the first user credentials from the user and obtaining the second user credentials from the user,
- iii. obtaining a print job corresponding to said document, said print job comprising print job metadata comprising said second user credentials, and
- iv. forwarding at least said print job metadata, comprising said second user credentials, to said authenticated printing system for said processing,
- wherein the steps of the method are performed by a processing server serving as an intermediary between the cloud storage system and the authenticated printing system.
