System and method for users of mobile computing devices to print documents

A print service is provided on a network, such as the Internet or a corporate intranet, for mobile computing devices, such as laptops, PDA's and Web cell phones, etc., to print documents. When the user of a mobile device wants to print a document, the mobile device is used to access the print service and send a print request that specifies the location the document on the network in terms of URL. In response, the print service validates the print request, retrieves the document, renders the document for printing, and prints the document as requested by the user. Alternatively, the document may be directly provided by the mobile device to the print service.
