ABSTRACT:
A terminal printer can simultaneously receive print data from a plurality of host devices. The terminal printer has one reception buffer memory to which reception buffers are allocated on the basis of number information of the connected host devices, and a buffer management memory which manages the reception buffer memory. The buffer management memory is configured by region which respectively store terminal addresses of the host devices using the reception buffers, and regions which respectively store serial numbers of lastly received packets in correspondence with the reception buffers. When a packet is received, the terminal address of the host device included in the packet is compared with the terminal addresses stored in the buffer management memory. Subsequently, the packet is stored into the reception buffer of the reception buffer memory which is designated by the coincident terminal address.
