Print control apparatus, image forming apparatus and method to select sheet type and test chart for performing different types of test printing

A control method for controlling a print control apparatus capable of communicating with a printing apparatus, including a sheet holding unit in which a sheet to be used for printing is held, for printing an image on the sheet held in the sheet holding unit, the print control apparatus including storage configured to store information regarding a test chart, wherein the information regarding a test chart includes a type of a sheet, an image to be used as a test chart, and a setting value of the printing apparatus in association with each other, the control method comprising:

• selecting a type of a sheet to be used for printing by the printing apparatus;
• selecting the image to be used as a test chart;
• displaying a setting screen in which the setting value of the printing apparatus stored in the storage is reflected, the setting value being determined based on the selected type of a sheet and the selected image;
• setting the setting value via the setting screen;
• determining whether a first type of test print or a second type of test print is to be performed for test printing in accordance with the set setting value;
• transmitting, to the printing apparatus, a test printing instruction, the set setting value and designation information to designate a location in which an image is stored wherein the image is stored for test print in a case where it is determined the first type of test print is to be performed for the set setting value, and transmit a test printing instruction, the set setting value, and predetermined test print data in a case where it is determined the second type of test print is to be performed for the set setting value;
• and
• by transmitting the test printing instruction, instructing the printing apparatus such that the printing apparatus outputs at least one test print page in accordance with the test printing instruction wherein, in the first type of test print, the test print page is output based on the image stored in the location designated by the designation information, the selected type of the sheet and the set setting value in association with the selected type of the sheet, and, in the second type of test print, the test print page is output based on the predetermined test print data, the selected type of the sheet and the set setting value.
