a control unit configured to cause the conveyance unit to hold the sheet onto which printing was performed by the printing unit; and a receiving unit configured to receive an ejection instruction for instructing to eject the sheet, wherein the control unit, in a case where the receiving unit receives the ejection instruction, controls the conveyance unit to eject the sheet to outside of the apparatus after a predetermined time has elapsed. ## Claims ### Claim 1 A printing apparatus comprising: a conveyance unit configured to convey a sheet to a printing unit configured to perform printing; a control unit configured to cause the conveyance unit to hold the sheet onto which printing was performed by the printing unit; and a receiving unit configured to receive an ejection instruction for instructing to eject the sheet, wherein the control unit, in a case where the receiving unit receives the ejection instruction, controls the conveyance unit to eject the sheet to outside of the apparatus after a predetermined time has elapsed. ### Claim 2 (depends on 1) The printing apparatus according to claim 1, wherein the conveyance unit is arranged downstream of the printing unit in a conveyance direction of the sheet, and includes a pair of ejection rollers for nipping and conveying the sheet, and the pair of ejection rollers nip the sheet onto which printing was performed by the printing unit. ### Claim 3 (depends on 2) The printing apparatus according to claim 2, wherein the conveyance unit, by resuming conveyance of the sheet by the pair of ejection rollers, ejects the sheet to the outside of the printing apparatus. ### Claim 4 (depends on 3) The printing apparatus according to claim 3, wherein the control unit controls the conveyance unit to make a conveyance speed for ejecting the sheet to the outside of the printing apparatus lower than a conveyance speed for printing by the printing unit. ### Claim 5 (depends on 1) The printing apparatus according to claim 1, wherein the control unit controls the conveyance unit to suspend conveyance of the sheet to the outside of the printing apparatus. ### Claim 6 (depends on 2) The printing apparatus according to claim 2, wherein the conveyance unit, by increasing an axial distance between the pair of ejection rollers, ejects the sheet to the outside of the printing apparatus. ### Claim 7 (depends on 1) The printing apparatus according to claim 1, further comprising: a determination unit configured to determine a size of the sheet, wherein the control unit, in a case where the determination unit determines that the size of the sheet is smaller than a predetermined size, controls the conveyance unit to eject the sheet to the outside of the printing apparatus regardless of the lapse of the predetermined time. ### Claim 8 (depends on 1) The printing apparatus according to claim 1, further comprising: a notification unit configured to, before the receiving unit receives the ejection instruction , notify information related to the predetermined time. ### Claim 9 (depends on 8) The printing apparatus according to claim 8, wherein the notification unit notifies a plurality of selection items related to a length of the predetermined time, and the control unit, after waiting for a time that corresponds to one of the plurality of selection items selected via the receiving unit, controls the conveyance unit to eject the sheet to the outside of the printing apparatus. ### Claim 10 (depends on 8) The printing apparatus according to claim 8, wherein the notification unit notifies via at least one of a display and a speaker. ### Claim 11 A printing apparatus comprising: a conveyance unit configured to convey a sheet to a printing unit configured to perform printing; a control unit configured to cause the conveyance unit to hold the sheet onto which printing was performed by the printing unit; and a receiving unit configured to receive an ejection instruction for instructing to eject the sheet, wherein the control unit, in a case where the receiving unit receives the ejection instruction, controls the conveyance unit to eject the sheet to outside of the apparatus in a different manner to that before execution of the holding of the sheet by the conveyance unit. ### Claim 12 (depends on 11) The printing apparatus according to claim 11, wherein the control unit controls the conveyance unit to make a conveyance speed for ejecting the sheet to the outside of the printing apparatus lower than a conveyance speed for printing by the printing unit. ### Claim 13 (depends on 11) The printing apparatus according to claim 11, wherein the control unit controls the conveyance unit so that a conveyance speed for ejecting the sheet to the outside of the printing apparatus is temporarily reduced. ### Claim 14 (depends on 11) The printing apparatus according to claim 11, wherein the control unit controls the conveyance unit to suspend conveyance of the sheet to the outside of the printing apparatus. ### Claim 15 (depends on 1) The printing apparatus according to claim 1, wherein the control unit, before the receiving unit receives the ejection instruction, controls the conveyance unit to hold an area that is not printed by the printing unit. ### Claim 16 (depends on 1) The printing apparatus according to claim 1, comprising: a notification unit configured to, before the receiving unit receive the ejection instruction, notify an instruction that prompts a user to hold the sheet to be ejected. ### Claim 17 (depends on 16) The printing apparatus according to claim 16, wherein the notification unit notifies via at least one of a display and a speaker. ### Claim 18 A control method of a printing apparatus having a conveyance unit for conveying a sheet to a printing unit configured to perform g printing, the method comprising: causing the conveyance unit to hold the sheet onto which printing was performed by the printing unit; receiving an ejection instruction for instructing to eject the sheet; and controlling, in a case where the ejection instruction is received the conveyance unit to eject the sheet to outside of the apparatus after a predetermined time has elapsed.
