PROBLEM TO BE SOLVED: To provide a printer which can suppress reduction in printing quality by preventing supply failure of liquid in each of a plurality of liquid channels.SOLUTION: A printer comprises a lower mounting part 811 which can mount a cartridge 311, a lead-out needle 831 which can lead out while ink from the lower mounting part 811 to a derivation channel 701A, and a head unit 100 which includes a plurality of nozzle arrangement regions 120. The derivation channel 701A branches off to connection channels 702A, 703A at a branching part 753A. The connection channels 702A, 703A are connected to first supply channels 711, 712 respectively at connection parts 754A, 755A. The first supply channels 711, 712 are connected to nozzle arrangements 121, 122 respectively. The connection channels 702A, 703A respectively include filter parts 681, 682. The channel resistance in the filter parts 681, 682 is larger than the channel resistance in the lead-out needle 831.SELECTED DRAWING: Figure 4 【課題】複数の液体流路のそれぞれにおける液体の供給不良を防止し、印刷品質の低下を低減できる印刷装置を提供する。【解決手段】プリンタは、カートリッジ３１１を装着可能な下装着部８１１と、下装着部８１１から白インクを導出流路７０１Ａへ導出可能な導出針８３１と、複数のノズル配置領域１２０を備えるヘッドユニット１００とを備える。導出流路７０１Ａは、分岐部７５３Ａにおいて、接続流路７０２Ａ，７０３Ａに分岐する。接続流路７０２Ａ，７０３Ａは、接続部７５４Ａ，７５５Ａにおいて、第一供給流路７１１，７１２のそれぞれに接続する。第一供給流路７１１，７１２は、ノズル配列１２１，１２２にそれぞれ接続する。接続流路７０２Ａ，７０３Ａは、フィルタ部６８１，６８２をそれぞれ備える。フィルタ部６８１，６８２における流路抵抗は、導出針８３１における流路抵抗よりも大きい。【選択図】図４
