Method and apparatus for printing from a mobile device

A method of printing an output document is disclosed. Initially stored data (3) to be incorporated in an output document to be printed is identified. The capabilities of a printer (2) selected to be utilised to print the output document are then determined. A format for the output document to be printed which is to incorporate the identified stored data (3) is then determined on the basis of the determined capabilities of a printer (2) selected to be utilised to print the output document. Render data (23a) suitable for printing by the selected printer (2) for printing an output document including the data corresponding to the identified stored data (3) in the determined format is then generated and the generated render data (23a ) is routed to a printer (2) which prints an output document using the render data (23a).
