Printers with positional sensors

A printer that is capable of data transmission via a network and receives print data to carry out printing, said printer comprising:

• a positioning unit that recognizes positional information representative of where said printer is located, wherein said positioning unit includes a positional information obtaining unit that obtains said positional information as a result of positioning by a positioning system connected therewith;
• a positional information output unit that outputs said recognized positional information via the network;
• a displacement detection unit that detects a displacement of said position of said printer;
• a positioning activation unit that activates said positioning unit to carry out the recognition of said positional information, in response to a detection of the displacement of the position;
• a decision unit that receives print data, said print data in itself includes the positional information for said printer, wherein said positional information is given as data comprising a combination of a latitude, a longitude, and an altitude, and determines whether said print data are to be printed by said printer, based on the positional information;
• and
• a sensor that recognizes a moving distance of the printer, wherein said displacement detection unit detects where the printer is located based on the moving distance recognized by the sensor, and
• said positioning system is a GPS (global positioning system) that obtains said positional information by utilizing a phase difference between microwaves sent from at least three satellites.
