Description

Printing control device, printing system, and recording medium Technical Field The present invention relates to a printing control device, a printing system, and a program. Background A printing system is known in which setting of a printer connected to a network is easier (see patent document 1). In the printing system described in patent document 1, a print control device, a data conversion server that converts print job data into a data format printable by a printing device, and the printing device are connected together via a network. However, in the printing system described in patent document 1, the number of data conversion servers is fixed, and thus the processing capacity is reduced when the print job data is large. In the printing system described in patent document 1, when the print job data is small, the processing capacity becomes excessive. Patent document 1 Japanese patent application laid-open No. 2014-49004 Disclosure of Invention The present disclosure provides an invention for solving the above-described problems, wherein a print control device includes a change control unit that performs control for changing the number or specification of one or more virtual data conversion servers that convert data of a print job corresponding to a print request to data corresponding to a printing device, based on a predetermined number related to the print request issued from a terminal device, and a distribution control unit that performs control for distributing the print job to the one or more virtual data conversion servers after the change. Further, one aspect of the present disclosure is a printing system including the printing control device described above, and the one or more data conversion servers. Further, one embodiment of the present disclosure is a program for causing a computer to execute a change control step of executing control of changing the number or specification of one or more data conversion servers for converting data of a print job corresponding to a print request to data corresponding to a printing apparatus based on a predetermined number related to the print request issued from a terminal device, and an allocation control step of executing control of allocating the print job to the one or more data conversion servers after the change.
