Processing-independent tablet interface for printing devices

A printing device comprising:

• a body;
• a printer power supply within the body;
• a printer processor within the body and connected to the printer power supply;
• printing components within the body and connected to the printer power supply and the printer processor;
• and
• a tablet interface device external to the body and connected to the printer processor and the printer power supply, wherein the tablet interface device comprises:
• a tablet processor;
• a USB connection electrically connected to the tablet processor and the printer power supply, wherein the USB connection of the tablet interface device is the only electrical and communication connection between the tablet interface device and the printing device;
• and
• a touchscreen surface electrically connected to the tablet processor, and
• wherein the tablet processor is adapted to operate independently of the printer processor by independently communicating with other devices external to the printing device and independently processing data without using processing resources of the printer processor.
