In a case where it is determined that the printing for the first print job and the second print job can be made continuously, print media to be used for printing for the second print job is fed to a conveyance path before completing outputting printouts for the first print job. ## Claims ### Claim 1 An image forming apparatus which performs printing based on a print job, the image forming apparatus comprising: a memory containing instructions; and at least one processor executing the instructions to: determine whether printing for a first print job and a second print job having been received after the first print job can be made continuously, in a case where it is determined that the printing for the first print job and the second print job can be made continuously, feed print media to be used for printing for the second print job to a conveyance path before completing outputting a printout for the first print job, and in a case where a number of copies to be printed for the first print job and a number of copies to be printed for the second print job are both greater than or equal to a predetermined number of copies, or in a case where the number of copies to be printed for the first print job and the number of copies to be printed for the second print job are both less than the predetermined number of copies, determine that the printing for the first print job and the second print job can be made continuously. ### Claim 2 (depends on 1) The image forming apparatus according to claim 1, wherein the instructions are further executed to, in a case where the number of remaining sheets to be printed for the first print job is greater than a threshold value, determine that the printing for the first print job and the second print job can be made continuously. ### Claim 3 (depends on 2) The image forming apparatus according to claim 2, wherein the threshold value is, out of the number of remaining sheets to be printed for the first print job, equal to the number of print media already fed. ### Claim 4 (depends on 1) The image forming apparatus according to claim 1, wherein the instructions are further executed to, in a case where a printing setting acquired from the first print job and a printing setting acquired from the second print job are the same, determine that the printing for the first print job and the second print job can be made continuously. ### Claim 5 (depends on 4) The image forming apparatus according to claim 4, wherein the printing setting includes at least any one of a size of print media, a type of print media, a printing side of print media, printing resolution, and the number of printing colors. ### Claim 6 (depends on 1) The image forming apparatus according to claim 1, wherein the instructions are further executed to instruct feeding of print media to the feed unit, wherein, in a case where it is determined that the printing for the first print job and the second print job can be made continuously, instructions are executed to feed print media to be used for printing for the second print job before completing feeding of print media used for printing for the first print job. ### Claim 7 An image forming method for performing printing based on a print job, the method comprising the steps of: determining whether printing for a first print job and a second print job having been received after the first print job can be made continuously, in a case where it is determined that the printing for the first print job and the second print job can be made continuously, feeding print media to be used for printing for the second print job to a conveyance path before completing outputting a printout for the first print job, and in a case where a number of copies to be printed for the first print job and a number of copies to be printed for the second print job are both greater than or equal to a predetermined number of copies, or in a case where the number of copies to be printed for the first print job and the number of copies to be printed for the second print job are both less than the predetermined number of copies, determining that the printing for the first print job and the second print job can be made continuously. ### Claim 8 (depends on 7) The image forming method according to claim 7, wherein, in a case where the number of remaining sheets to be printed for the first print job is greater than a threshold value, it is determined that the printing for the first print job and the second print job can be made continuously. ### Claim 9 (depends on 8) The image forming method according to claim 8, wherein the threshold value is, out of the number of remaining sheets to be printed for the first print job, equal to the number of print media already fed in the feeding step. ### Claim 10 (depends on 7) The image forming method according to claim 7, wherein, in a case where a printing setting acquired from the first print job and a printing setting acquired from the second print job are the same, it is determined that the printing for the first print job and the second print job can be made continuously. ### Claim 11 (depends on 10) The image forming method according to claim 10, wherein the printing setting includes at least any one of a size of print media, a type of print media, a printing side of print media, printing resolution, and the number of printing colors. ### Claim 12 (depends on 7) The image forming method according to claim 7, wherein, in a case where it is determined that the printing for the first print job and the second print job can be made continuously, print media to be used for printing for the second print job is instructed to be fed before completing feeding of print media used for printing for the first print job. ### Claim 13 (depends on 1) The image forming apparatus according to claim 1, wherein, in a case where it is determined that the printing for the first print job and the second print job can be made continuously, print media to be used for printing for the second print job is fed to a conveyance path before completing outputting of all printouts for the first print job. ### Claim 14 (depends on 1) The image forming apparatus according to claim 1, wherein, in a case where the number of copies to be printed for a print job is less than the predetermined number of copies, the print media are conveyed at a first conveyance speed, and in a case where the number of copies to be printed for a print job is greater than or equal to the predetermined number of copies, the print media are conveyed at a second conveyance speed which is faster than the first conveyance speed. ### Claim 15 (depends on 7) The image forming method according to claim 7, wherein, in a case where it is determined that the printing for the first print job and the second print job can be made continuously, print media to be used for printing for the second print job is fed to a conveyance path before completing outputting of all printouts for the first print job. ### Claim 16 (depends on 7) The image forming method according to claim 7, wherein, in a case where the number of copies to be printed for a print job is less than the predetermined number of copies, the print media are conveyed at a first conveyance speed, and in a case where the number of copies to be printed for a print job is greater than or equal to the predetermined number of copies, the print media are conveyed at a second conveyance speed which is faster than the first conveyance speed.
