BACKGROUND

Printers are typically controlled via direct physical interaction between operators and printers, e.g. using a control panel, touch screen or the like implemented on the printer. Printers may also be controlled over local networks, e.g. from a personal computer connected to the same local network. Controlling such printers via commands received from servers outside the above local network, e.g. relayed through such servers from operators using mobile devices or the like, is typically not feasible, however.
