Printing apparatus and control method

摘要

A printing unit comprises: a communication unit configured to be connected to a communication line to which a plurality of print data transmission devices are connectable; a memory unit configured to store print data received by the communication unit; a printing unit including a roller mechanism for sending recording paper and being configured to drive a printing mechanism based on the print data stored in the memory unit to print on the recording paper; and a control unit configured to determine, in response to receiving a connection request from a first print data transmission device by the communication unit, whether or not the printing apparatus is connected to another print data transmission device for communication, cause the communication unit to send as a reply a first response for causing the first print data transmission device to wait to start transmission of print data when the printing apparatus is connected to the another print data transmission device for communication, and cause the communication unit to send as a reply a second response for allowing the first print data transmission device to transmit the print data after the printing apparatus and the another print data transmission device end the communication connection.

1. A printing apparatus, comprising:
a communication unit configured to be connected to a communication line to which a plurality of print data transmission devices are connectable; a memory configured to store print data received by the communication unit; a printing device including a roller mechanism for sending recording paper and configured to drive a printing mechanism based on the print data stored in the memory unit to print on the recording paper; and a controller configured to determine, in response to receiving a connection request from a first print data transmission device by the communication unit,
whether or not the printing apparatus is connected to another print data transmission device for communication,cause the communication unit to send as a reply a first response for causing the first print data transmission device to wait to start transmission of the print data when the printing apparatus is connected to the another print data transmission device, andcause the communication unit to send as a reply a second response for allowing the first print data transmission device to transmit the print data after the printing apparatus and the another print data transmission device end the communication connection.
