A printing managing apparatus comprising: an attribute specification information converting unit that converts pieces of individual job attribute information of attribute specification information that is transmitted from a printing control apparatus and contains pieces of individual job attribute information indicating job attributes that can be set in the printing control apparatus and sets of attribute values that can be designated for the respective job attributes into respective pieces of common job attribute information using job attribute correlating information that is stored in advance and that correlates pieces of individual job attribute information used in plural respective printing control apparatus with common job attribute information for each job attribute that can be set in print job information so as to be common to the plural printing control apparatus as transmission destination candidates of the print job information; a manipulation control processing unit that links manipulation target print job information transmitted from outside with the attribute specification information using pieces of common job attribute information indicating job attributes that are set in the manipulation target print job information, and displays the manipulation target print job information in a print job information manipulation picture that is set so as to be common to the plural printing control apparatus to allow a manipulation on the displayed print job information; and a print job information converting unit that converts pieces of individual job attribute information indicating job attributes that are set in acquired print job information into respective pieces of common job attribute information using the job attribute correlating information, wherein the print job information converting unit converts pieces of individual job attribute information indicating job attributes that are set in print job information transmitted from outside into respective pieces of common job attribute information using the job attribute correlating information, and stores the resulting pieces of common job attribute information in a print job information memory; and the manipulation control processing unit displays the print job information manipulation picture by referring to the print job information memory; wherein, if no controller ID is specified in the attribute specification information that is transmitted from the printing control apparatus or a correct controller ID is set but a printer model name is contained in such information as attribute specification information, the specification information converting unit converts the printer model name into a controller ID by referring to apparatus conversion information which is prepared in advance and is set in such a manner that pieces of controller IDs of the respective printing control apparatus are correlated with respective printer model names to identify the information transmission source printing control apparatus. an attribute specification information converting unit that converts pieces of individual job attribute information of attribute specification information that is transmitted from a printing control apparatus and contains pieces of individual job attribute information indicating job attributes that can be set in the printing control apparatus and sets of attribute values that can be designated for the respective job attributes into respective pieces of common job attribute information using job attribute correlating information that is stored in advance and that correlates pieces of individual job attribute information used in plural respective printing control apparatus with common job attribute information for each job attribute that can be set in print job information so as to be common to the plural printing control apparatus as transmission destination candidates of the print job information; a manipulation control processing unit that links manipulation target print job information transmitted from outside with the attribute specification information using pieces of common job attribute information indicating job attributes that are set in the manipulation target print job information, and displays the manipulation target print job information in a print job information manipulation picture that is set so as to be common to the plural printing control apparatus to allow a manipulation on the displayed print job information; and a print job information converting unit that converts pieces of individual job attribute information indicating job attributes that are set in acquired print job information into respective pieces of common job attribute information using the job attribute correlating information, wherein the print job information converting unit converts pieces of individual job attribute information indicating job attributes that are set in print job information transmitted from outside into respective pieces of common job attribute information using the job attribute correlating information, and stores the resulting pieces of common job attribute information in a print job information memory; and the manipulation control processing unit displays the print job information manipulation picture by referring to the print job information memory;
