A server for connection to a client via a network, the client being operable to transmit user-input to the server over the network and to receive user-output from the server over the network. The server comprises a network interface for connection to the network; and a processor coupled to the interface. The processor is operable to remotely host execution of an application for the client. The application is for receiving the user-input from the client over the network and for generating the user-output for transmission to the client over the network. The server implements a universal printer driver operable to generate a universal printer file from the application based on a request for a file to be printed that is embedded in the user-input. The server is further operable to transmit the universal printer file over the network. The universal printer file has a format amenable to interpretation by a universal print file reader into a printer file suitable for printing by a printing device.
