Patent ID: 8783813

Claim:
A printer comprising: a plurality of discharge control devices that are configured to be connected to at least one of a plurality of discharge port groups having a plurality of discharge ports capable of discharging liquid, and to control discharge of the liquid by the connected discharge port group based on print data, the print data being data to discharge the liquid by the connected discharge port group; a control data output device that is configured to output the print data to each of the discharge control devices; a connection device that includes a first connection port capable of connecting to the control data output device and a plurality of second connection ports that are capable of individually connecting to the at least one of the plurality of discharge port groups and that are capable of individually connecting to the first connection port such that data transmission is possible; a connection control device that is configured to control data transmission between the first connection port and the plurality of second connection ports; a processor; and a memory configured to store computer-readable instructions, wherein the computer-readable instructions cause the processor to perform processes comprising: starting output of specified print data from the control data output device, via a connection device controlled by a connection control device, to a specified discharge control device which is one of the plurality of discharge control devices that are each connected to one of the plurality of second connection ports and which is a target to perform processing that outputs print data, the specified print data being the print data to discharge the liquid by the discharge port group connected to the specified discharge control device; and outputting subsequent print data from the control data output device, via the connection device, to the specified discharge control device that is connected to the second connection port, the subsequent print data being data relating to a specified discharge target onto which the liquid is to be discharged by the discharge port group connected to the specified discharge control device, based on the specified print data for which output has been started.
