Sending a print job through a mobile device is referred to as mobile printing. But why would you require a portable printer? Consider this. Printers were once physically attached to devices. Employees have to start the print cycle from the connected device by themselves as a result. While wireless communication from numerous devices superseded this, the dated "bulky printer" made portability impractical. There was a demand for a printing device that could speed up and streamline procedures because of doorstep services and an active lifestyle.
