Print data transfer method, printing system and printer device

A printing system comprising a print data supply device and a printer device which are connected to each other via a transmission channel,

• wherein the print data supply device holds print data, and
• the printer device includes:
• a unit operable to receive a print request which is issued together with attribute information of the print data supply device in order to print the print data held by the print data supply device;
• a unit operable to request, in response to the print request, the print data supply device to transmit the print data based on the attribute information;
• a unit operable to receive the print data which is transmitted from the print data supply device in response to the data request;
• and
• a unit operable to print the print data.

A printer device which is connected with a print data supply device which holds print data via a transmission channel, the printer device comprising:

• a unit operable to receive a print request which is issued together with attribute information of the print data supply device in order to print the print data held by the print data supply device;
• a unit operable to request, in response to the print request, the print data supply device to transmit the print data based on the attribute information;
• a unit operable to receive the print data which is transmitted from the print data supply device in response to the data request;
• and
• a unit operable to print the print data.

A program for a printer device that forms an image based on received print data, the program causing a computer to function as:

• a unit operable to receive a print request which is issued together with attribute information of the print data supply device in order to print the print data held by the print data supply device;
• a unit operable to request, in response to the print request, the print data supply device to transmit the print data based on the attribute information;
• a unit operable to receive the print data which is transmitted from the print data supply device in response to the data request;
• and
• a unit operable to print the print data.

A print file acquisition system comprising:

• a storage unit operable to store link path information which specifies a storage location of a print file;
• a conversion unit operable to convert a relative path into an absolute path when all or a part of the link path information acquired from the storage unit is the relative path, the relative path indicating a relative location of the print file from a predetermined reference location and the absolute path indicating an absolute location of the print file;
• and
• an acquisition unit operable to acquire the print file, the print file being able to be specified with the absolute path obtained by the conversion by the conversion unit.

A print data transfer system comprising a print data supply device and a printer device which are connected to each other via a transmission channel, for transferring print data from the print data supply device to the printer device, the system further comprising:

• a network information acquisition unit operable to acquire network connection information of the print data supply device and the printer device after bus reset;
• a connection restoration unit operable to restore the connection for the print data transfer between the print data supply device and the printer device based on the network connection information obtained from the network information acquisition unit;
• a print request retransmission unit operable to retransmit a print request based on the network connection information obtained from the network information acquisition unit;
• and
• an acquisition unit operable to acquire a print object based on the print request retransmitted by the print request retransmission unit.
