Interface device and printer

A printer, comprising:

• a plurality of interface circuits, each respectively corresponding to a plurality of different transmission paths, configured to sequentially acquire a plurality of packets formed by dividing data which is an object of any one of plural types of information processing via the corresponding transmission paths;
• a reception buffer;
• a print engine configured to print an image on a print medium;
• and
• a processor configured to associate the packet acquired by each of the plurality of the interface circuits with an identification code for identifying the interface circuit that acquired the packet, write the packet with a different identification code to the reception buffer in a mixed state, sequentially read a plurality of packets associated with the same identification code among the packets stored in the reception buffer from the reception buffer, and start printing by the print engine by using the read packet.

A method of print processing, comprising:

• sequentially acquiring, by a device comprising a processor, a plurality of packets formed by dividing data which is an object of any one of plural types of information processing via different the transmission paths corresponding to a plurality of interface circuits;
• associating, by the device, the packet acquired by each of the plurality of the interface circuits with an identification code for identifying the interface circuit that acquired the packet;
• writing, by the device, the packet with a different identification code to a reception buffer in a mixed state;
• sequentially reading, by the device, a plurality of packets associated with the same identification code among the packets stored in the reception buffer from the reception buffer;
• and
• delivering, by the device, the read packets to information processing on the data which is a basis of the packet.
