Abstract:
1. A print data processing apparatus that controls, via hardware implementation, data transmitted to and received from a printer, comprising: an extension attaching unit that selectively attaches one of a first extension to print data and a second extension to control process request data that requests the printer to perform a control process that is different from a print process and corresponds to a kind of the second extension, prior to sending the one of the print data with the first extension and the control process request data with the second extension to the printer; and a transmission performing unit that transmits the print data or the control process request data to the printer, wherein the print data is data associated with a particular print job to be outputted by the printer, wherein the control process request data is data unrelated to any particular print job, that is not to be printed or processed for printing, and is configured to cause the printer to perform a control process other than print output or image processing, wherein the control process includes plural kinds of control processes, and wherein the second extension includes a plurality of second extensions, each of which corresponds to a respective one of the plural kinds of control processes.
