PRINTER

To improve the productivity of double-side printing, with a simple configuration, in a printer.SOLUTION: A printer 1 comprises: a printing unit 40; a print conveyance unit 50 which conveys a sheet P which is one example of a medium in the printing unit 40; an equal speed conveyance unit 33 which conveys the sheet P at an equal speed of a variable conveyance speed in a circulating route R2 for side printing; a resist roller pair 31 to which the sheet P conveyed toward the printing unit 40 is abutted; and a control unit 81 which determines a conveyance schedule of the sheet P, on the basis of a first conveyance route length L1 between a conveyance direction downstream side end part (guide roller 55) of the print conveyance unit 50 and a conveyance direction upstream side end part (equal speed roller pair 33a) of the equal speed conveyance unit 33 (and at least one of a second conveyance route length between the conveyance direction downstream side end part of the equal speed conveyance unit and the resist roller pair), and a sheet length L0 in the conveyance direction of the sheet P.SELECTED DRAWING: Figure 5 【課題】印刷装置において、簡素な構成で、両面印刷の生産性を向上させる。【解決手段】印刷装置１は、印刷部４０と、この印刷部４０において媒体の一例である用紙Ｐを搬送する印刷搬送部５０と、面印刷用の循環経路Ｒ２において用紙Ｐを可変の搬送速度で等速搬送する等速搬送部３３と、印刷部４０に向けて搬送される用紙Ｐが突き当てられるレジストローラ対３１と、印刷搬送部５０の搬送方向下流側端部（ガイドローラ５５）と等速搬送部３３の搬送方向上流側端部（等速ローラ対３３ａ）との間の第１搬送経路長Ｌ１（及び、等速搬送部の搬送方向下流側端部とレジストローラ対との間の第２搬送経路長のうち少なくとも一方）と、用紙Ｐの搬送方向における用紙長さＬ０とに基づいて、用紙Ｐの搬送スケジュールを決定する制御部８１とを備える。【選択図】図５
