Further, by providing a job chasing function on the printer driver side, detailed setting can be done to extract history information of the job chasing function. The detailed setting to extract history information to chase a job can be done only by a specific administrator or user so that the job can be reliably chased, whereas the administrator or user can obtain desired history information. Accordingly, a precise jog chasing system can be established. ## Claims ### Claim 1 A printing system including a printing apparatus and a management server connected to an information processing apparatus via a communication medium, wherein the information processing apparatus comprises: a print data transmission unit that transmits print data to the printing apparatus; an extraction unit that extracts image data corresponding to the transmitted print data; and a generating unit that generates data for chasing from the extracted image data, wherein the management server comprises: a setting unit that sets setting information to instruct a method of generating data for identifying content of the print data as the data for chasing, and wherein the generating unit generates the data for chasing based on the setting information set by the setting unit. ### Claim 2 (depends on 1) The printing system according to claim 1, wherein the setting information includes, as the method, information of at least one of the number of bits of the image data to be extracted, resolution and a compressing method. ### Claim 3 (depends on 1) The printing system according to claim 1, wherein the data for chasing generated by the generating unit is smaller in size than the print data corresponding to the data for chasing. ### Claim 4 An information processing apparatus capable of communicating with a printing apparatus and a management server, the information processing apparatus comprising: a print data transmission unit that transmits print data to be printed by the printing apparatus to the printing apparatus;
